Safety Precautions

To complete your guitar kit safely, also ensure you have the following on hand, and a wellĀ ventilated work space to work in.Ā 

Protective eyewearĀ 

Use protective safety glasses or a genuine face shield, not regular prescription, reading, orĀ sunglasses.Ā 

Disposable glovesĀ 

Use disposable gloves if applying stains or oil finishes directly to the guitar.Ā Ā 

MasksĀ 

Use an N95 rated dust mask for sanding and an R95 rated particle mask for finishing.Ā If using water based finishing products an N95 dust mask may suffice for both sanding andĀ finishing, but be sure to check the finishing suppliers recommendations first. Paint fumes areĀ dangerous.Ā 

A well ventilated work areaĀ 

Ensure your work space is well ventilated, especially when finishing to prevent a build up ofĀ potentially toxic fumes.

Making your DIY Guitar PlayĀ &Ā Sound GreatĀ 

There are four stages to building a great kit guitar, these are:Ā 

1. Preparation and finishingĀ 

The finished surface appearance of your guitar e.g. staining, painting, or applying aĀ hand rubbed oil finish.Ā 

2. Hardware InstallationĀ 

Fitting the tuners, strap buttons, bridge, and pickups.Ā 

3. Connecting the electronicsĀ 

Connecting the pickups to the input jack, and incorporating a pickup selector andĀ volume and tone potentiometers.Ā 

4. Final SetupĀ 

Adjusting the neck relief, action, intonation and pickup height.Ā 

We’ll cover each of these below, starting with preparation and finishing.Ā 

Before You Start: Let Your Kit Acclimate

Unbox it and leave it in your build room for at least 1 week, or 2–3 weeks in very dry or humid places, before you sand, fit or finish anything. How to acclimate your kit →

1. Preparation and finishingĀ 

Inspecting and prepping the body

Once unboxed, carefully inspect the guitar body and neck under decent light.Ā Ā 

Identify problem areas, as these should be addressed early on before commencing theĀ project.

inspecting the body

This includes large dents that require filling, deep scratches that require sandingĀ and glue residue on the surface of the guitar that will prevent your finish from beingĀ absorbed evenly.

Glue stains are only a potential issue for guitars with binding, and/or a veneer top.

Once you have identified problem areasĀ you can begin prep sanding the guitar.Ā Ā 

sanding the guitar

  1. Start by sanding the entire bodyĀ using 180 grit sandpaperĀ 
  2. Follow that up with 240 gritĀ paper. If you are applying a stain directly to the raw wood sand up to 400 grit, butĀ sanding any smoother than this may begin to affect how well the stain is absorbed.Ā 
  3. Once you have completed sanding up to 240 grit, wipe a small amount of moisture onĀ the surface of the guitar. Using denatured alcohol is a good option here as itĀ evaporates before it is absorbed into the timber, but water will also suffice. This willĀ raise the grain of the timber which can then be sanded flat. Generally grain will onlyĀ raise once, so you can be confident you won’t have any problems during the finishingĀ process.Ā Ā

Dry Fitting the Neck

You should also check the neck fit. While the STH is a bolt-on neck guitar, it’s still importantĀ to dry fit the neck and check how well the neck fits the neck pocket, along with neckĀ alignment, neck angle and scale length.Ā 

Insert the NeckĀ 

insert the neck

First push the heel gently into the backĀ of the neck pocket, then push the neckĀ 
down flat.

This reduces the risk of chipping the thinĀ edges of the neck pocket before theĀ 
neck has been installed.

Check the scale length

You can check the location of your bridge post holes with regard to scale length byĀ measuring the distance from the edge of the nut closest to the fretboard and the middle ofĀ the 12th fret and then doubling that number.Ā 

An STH guitar kit should have a scale length of 25.5ā€ or 650mm.Ā Ā 

Ā 

If your scale length appears out by a few mm, keep in mind the position of the bridge isĀ angled to compensate for the additional mass of the thicker bass strings and the saddles canĀ be adjusted forward or back via the intonation adjustment screws.

Check the neck fit

The neck, once inserted into the neck pocket, should have very little sideways movement. IfĀ there is a gap on either side of the neck, you may need to shim the neck by cutting smallĀ sections of scrap wood with a craft knife and gluing these to the sides of the neck pocket. Otherwise smaller gaps can be filled prior to finishing using a filler.Ā 

Recommended:Ā Fixing Cracks & LooseĀ Neck Joints Caused by Humidity

Check the neck angleĀ 

Keeping the bridge and steel ruler in place after checking your neck alignment, run the steelĀ ruler along the fretboard and over the bridge. The steel ruler should sit just above the saddlesĀ on the bridge when the bridge is sitting flat against the body.Ā 

Cutting the HeadstockĀ 

If shaping your headstock, start out byĀ sketching out some rough concepts before transferring the chosen design toĀ paper at the correct size. WhenĀ designing your headstock be sure toĀ leave a margin of at least 15mm from theĀ last tuning hole and the edge of theĀ headstock (the equivalent distanceĀ between the tuning peg holes).

cut the shape out

  1. Once you have a completedĀ design at the correct size cut the shapeĀ out and glue it to a thin scrap piece ofĀ timber to be used as a template. (YouĀ can also use cardboard which in manyĀ cases will be easier to work with).Ā 
  2. Using a coping saw, jigsaw, orĀ ideally a bandsaw cut out the headstock shape and sand the edges of yourĀ template smooth.Ā 
  3. Taking a small clamp, clamp theĀ template to the headstock and carefully trace the outline.Ā 

From there you can either cut the new headstock shape using the template as a guide, orĀ remove the clamps and cut following the outlines you just made.Ā 

When cutting out your headstock shape protect the neck of the guitar when cutting, cut wellĀ outside the lines to allow room for sanding and keep your saw as vertical as possible toĀ ensure straight lines on your headstock.Ā 

If unsure keep the design simple. A well executed simple design is better than a poorlyĀ executed complex one. Once complete, sand the edges until as smooth as the rest of theĀ body and neck.Ā 

Masking

Before we startĀ grain filling andĀ finishing we shouldĀ mask the neckĀ pocket, and bodyĀ cavities of theĀ guitar.

mask the neck pocket

Mask the tuningĀ peg holes on theĀ headstock to keepĀ the holes clean,Ā along with theĀ holes for the bridgeĀ and tailpiece andĀ pay special attention to the truss rod. You should also mask the fretboard when spraying theĀ back of the neck.Ā 

If your guitar has binding you can either attempt to mask off the binding, which in mostĀ cases will mean some finish still permeates the masking tape and will need to be removed, orĀ not masking, and scraping the binding clean with a razor blade before spraying your clearĀ coats.Ā 

I’d normally scrape the binding as this is a more effective use of time, rather than attemptingĀ to mask. But it’s best to mask the binding if you notice any cracks as the finish you apply willĀ permeate the binding staining it permanently.Ā 

Grain Filling

Grain filling is optional, and mostly depends on the wood your guitar is made from andĀ whether you are aiming for a flat finish.Ā Ā 

grain filling

If your guitar is made from an open grain timber such as Oak or Mahogany, the open pores ofĀ the timber will prevent a flat finish unless filled.Ā 

Basswood for the most part is optional. In most cases it’s advisable to grain fill but if paintingĀ a solid color you can get by using a primer which will level and seal the surface.Ā 

If you are staining, depending on the product you are using, you can grain fill either before orĀ after. In most cases I’ve found grain filling first results in a more even application, and a betterĀ result.Ā 

There are a number of different grain fillers available, including solvent, water and oil basedĀ options, along with pre-tinted options. Oil based grain fillers penetrate deeper into the wood,Ā but water is obviously easier to work with with regard to drying times and clean up.Ā 

We’ll be using an ebony tinted grain filler in the images below. Using a tinted grain filler is aĀ great option if you would like to accentuate the grain pattern of the guitar as the excess willĀ be removed when sanding but the filler used to fill the pores will remain in place andĀ emphasize the grain pattern of the wood under a transparent finish.Ā 

Below are the steps required for applying grain fill:Ā 

  1. Mix up enough product to grain fill the entire guitar. Follow the recommendations forĀ the product you are using in terms of application, cleanup and safety, then mix yourĀ grain fill into a workable paste in a spare container.Ā 
  2. Apply to the guitar using a clean rag, working in line with the grains pattern of theĀ wood. Next, work across the grain really pushing the grain fill into the wood, makingĀ several passes.Ā 
  3. Once finished applying, leave the guitar for ten minutes and then wipe away anyĀ excess using a clean damp rag.Ā 
  4. Once dry, sand back to the surface level of the guitar, working through the grades ofĀ sandpaper from 120 grit to 240. Sand sufficiently to remove the excess grain fill butĀ not enough to dig into the wood and create more open pores.Ā 
  5. Inspect the surface of the guitar and repeat the process if required.Ā 

FinishingĀ 

It’s beyond the scope of this guide to cover every available way to finish an electric guitar butĀ below are a few rules that apply to almost all finishing options:Ā 

finishing guitar kit

  • Carefully consider your finishing options with regard to how protective they are andĀ how they might affect tone along with aesthetics.Ā 
  • Choose your type of finish based on the wood itself. For example, it would be a shameĀ to cover up a beautiful grain pattern with a solid color finish. Alternatively, staining aĀ less figured piece of basswood for example may not provide a great aesthetic either.Ā 
  • Wear gloves and a mask and work in a well ventilated area as required. Fumes fromĀ some finishing products can be toxic.Ā 
  • Clean the body of the guitar using a product that includes a degreasing agentĀ Ā 
  • Wear disposable gloves when handling the guitar after cleaning.Ā 
  • Make sure you are working in a relatively dust free environment and make sure toĀ clean the cavities of the guitar body thoroughly after sanding. Dust accumulates inĀ the cavities of the guitar, and when turning the guitar over that dust will becomeĀ airborne.
  • If staining, make sure to wipe away any excess that hasn't been absorbed after approximately ten minutes.Ā Ā 
  • Be aware of the compatibility of the products you use. If painting using spray cans I’dĀ recommend using the same brand and type of paint for your seal coat, color coat andĀ clear coats.Ā 
  • If you have to spray outside avoid spraying on windy days.Ā 
  • Spray the sides of the body first. That way when spraying the front and back you willĀ be spraying over any overspray from the sides of the guitar.Ā 
  • Don’t spray heavy coats. In many cases, several lighter coats are a better option thanĀ 1-2 heavy coats due to the potential for runs.Ā 
  • Check your binding for cracks. If cracks are present, mask the binding prior to applying a colored finish or the finish will penetrate the binding and become impossible to restore to its original state.Ā 
  • Don’t apply too many coats within recommended drying times. If you spray moreĀ than 3 coats in a day for example, your first coat may have trouble curing.Ā Ā 
  • If you are using steel wool on the body of the guitar prior to finishing ensure you remove all fibers from the steel wool.Ā 
  • Always hang your guitar in a cool dry environment. Do not leave your guitar outside toĀ dry, it will attract dust.Ā 
  • In most cases, you can respray within an hour. If you leave it longer than this, you mayĀ need to leave the guitar for 24 hours and then lightly scuff up the paint with 600 - 800Ā grit sandpaper to ensure the ensuing coats will adhere to the previous coats. (ThisĀ depends on the product you are using, so check the label).Ā

Installing the neckĀ 

Now that the finishing stage is complete we can safety install our neck.

installing the neck

Within your packaging there will be a neck plate, neck plate cushion and four long screws.Ā 

placing the neck plate cushion

Place the neck into the neck pocket andĀ ensure it is pushed right up into theĀ 
back of the cavity.Ā Ā 

Place the black neck plate cushionĀ followed by the chrome neck plate (asĀ 
per the image above) and then looselyĀ place the 4 screws, but don’t beginĀ 
tightening these yet.Ā 

Next, double check your alignment and begin installing the screws. Install the top left screwĀ first, followed by the bottom right screw, working diagonally. Once all screws are in place,Ā tighten and double check the neck alignment.Ā 

2. Hardware InstallationĀ 

Installing hardware usually involves installing the tuners, strap buttons, bridge, string trees,Ā and pickups. There are some best practices to follow including drilling pilot holes andĀ aligning your hardware correctly which we’ll cover in more detail below.

Pilot HolesĀ 

Drill pilot holes for all screws used on theĀ body and neck of the guitar. The smallĀ 

screws used for securing your tuners forĀ example are small, fragile and easilyĀ 
stripped.Ā Ā 

Whenever installing hardware:Ā 

  1. Use masking tape on the guitar to mark the location of the hole using a pen (pencilsĀ usually don’t result in sharp lines on masking tape).Ā 
  2. Mark the location of the hole making an indentation in the wood through the masking tape using a hole punch or similar tool.Ā 
  3. Decide on the correct size drill bit (ā…” thickness of the screw) and mark the drill bitĀ depth using a small piece of masking tape at approximately 2/3 the depth of theĀ screw to be installed.Ā Ā 
  4. Always aim to drill your holes straight. If you have a drill press this is preferred.Ā 
  5. Use a countersink drill bit (or similar) to chamfer the edges of any holes in the body ofĀ the guitar, especially if painted using a solid color finish, to prevent chipping.Ā 

You may want to drill less than ā…“ depth on less dense timbers such as Mahogany andĀ Basswood.Ā 

Installing strap buttonsĀ 

Strap buttons not only support yourĀ guitar when playing standing up, theĀ  placement of the strap buttons alsoĀ affects the balance of the guitar. On anĀ STH guitar, the rear strap button is located in the center of the lower bout. The front strapĀ button is inserted into the top horn on a downward facing angle

install strap buttons

Follow the method described above for all hardware installation including using paintersĀ marking tape for marking the location of pilot holes, and drilling to the correct size.Ā 

Installing the TunersĀ 

STH guitar kits utilize inline tuners, soĀ you won’t need to separate your tunersĀ  into left and right.

installing the tuners

  1. Start by inserting the tuner in theĀ back of the headstock with theĀ mounting hole facing back toward theĀ body.Ā 
  2. Place the washers over theĀ tuning posts, then place the bushingsĀ and install the tuners by handĀ tightening.Ā 
  3. Align the tuners using a steel ruler (see image below).Ā Ā 
  4. Mark the location of the mounting screws, drill your pilot holes and install the smallĀ screws.Ā 
  5. Remove the protective covering by firmly pressing masking tape onto the back ofĀ each tuner and removing both the covering and masking tape in one action.Ā 

aligning the tuners

You can also install the first and last tuner, and using a steel rule mark a straight line betweenĀ them on masking tape to ensure a straight line to mark out the location of the pilot holes.Ā 

Installing and grounding the bridgeĀ 

Next, we need to insert the ground wireĀ into the bridge post hole and insert theĀ 
bridge bushing.

There should be a loose black groundĀ wire in your packaging. Look for a smallĀ 

hole on the side of the bridge post holeĀ nearest to the control cavity. ThereĀ  should be a small hole just large enoughĀ to thread the ground wire through to the bridge pickup cavity.Ā 

insert the ground wire

  1. Remove a few mm of the PVC coating and expose the bare wires.Ā Thread the wire, ensuring the bare wires are exposed and will sit flush against the side of the bridge or tailpiece post bushing once installed.Ā 
  2. Make a small ā€˜hook’ in the top of the wire so the ground wire sits at the top of theĀ bridge or tailpiece post hole before installing the bushing.Ā Ā 
  3. Remove the post from the bushing.Ā 
  4. Insert the bushing into the predrilled hole, ensuring the ground wire ends up sittingĀ flush against the bushing. In many cases you may require a rubber mallet to force theĀ bushing into place.Ā 
  5. Screw the bridge posts to the bridge bushings and the tailpiece posts to the tailpieceĀ bushings.Ā 
  6. You can then fit the bridge over the bridge posts, but leave the tail piece for now as itĀ will not remain in place until the strings are installed.Ā 

Installing the Floating TremoloĀ 

Next we’ll install our floating tremolo system. The design is based on offset-body guitars. The tremolo arm sits between the high E and B strings once installed, so makeĀ sure you position it with the stop bar (the raised section) closer to the back of the guitar.Ā 

installing floating tremolo

The simplest way to install the tremolo system is to push it hard against the front edge of theĀ cavity to ensure it is square to the cavity and then mark your pilot holes. The tremolo systemĀ can be adjusted by raising or lowering the spring, which is adjusted by turning the screw inĀ the center of the base plate, just beside the tremolo bar when installed.Ā 

installing floating tremolo

Installing the String TreesĀ 

String trees serve to increase the breakĀ angle from the nut to the tuners, for theĀ 
high Em B, G, and D strings, providingĀ greater stability for the nut andĀ 
preventing strings moving around inĀ their slots.Ā  Ā 

installing string strees

This is fairly typical of bolt-on neck guitars, as the majority of necks haveĀ much less of a backward tilt comparedĀ to set-neck single-cut guitars which typically do not utilize string trees.Ā 

You should have two string trees in your packaging. One will feature a longer barrel which isĀ to be used for the string tree between the D and G strings, with the shorter one reserved forĀ the B and high E strings.Ā 

installing string trees and strings

To install your string trees, you will firstĀ need to install your strings to allow forĀ 
perfect alignment.Ā Ā 

Once the strings are in place lay the topĀ face of the string trees across the E,BĀ 
and D and G strings.Ā Ā 

Align the D and G string tree betweenĀ the first and second tuning post and theĀ 
D and E string tree in line with the second tuning post.Ā Ā 

Once in place mark the holes as we have done for all hardware up to this point and drill yourĀ pilot holes before placing the string tree barrels in place and screwing the string trees inĀ place.Ā 

Installing PickupsĀ 

We’ll be installing soap bar style P90 pickups.Ā  Ā 

installing pickups

As this style of pickup has no obvious discerning features that allow us to differentiateĀ between the neck and bridge, flip the pickup over and look for either an ā€˜N’ for neck, or ā€˜B’ forĀ bridge. From there:Ā 

  1. Thread the pickup wires for the neck pickup through the hole to the rear of the neckĀ pickup cavity and through the hole in the side of the bridge pickup cavity.Ā Ā 
  2. Next, install the bridge, also threading the wires through the hole in the side of theĀ cavity leading to the electronics cavity.Ā 
  3. Position the pickups at the very front of the pickup cavity and then align the outside EĀ strings to the individual pole pieces corresponding to the low E and high E. (you canĀ also use a square to check the alignment relative to the edge of the fretboard).Ā 
  4. The pickups are direct mount, meaning the screws pass through the body. Mark yourĀ pilot holes as done previously, directly through the holes on either side of theĀ magnetic pole pieces corresponding with the G and D strings.Ā Ā 
  5. Remove the pickups from the cavity, drill the pilot holes and install the screws.Ā 

3. Connecting the electronicsĀ 

SolderingĀ 

If you haven’t soldered before you’re going to need a soldering iron, solder, and a dampĀ sponge to clean the tip of your iron. I’d also recommend practicing before committing solderĀ to your electrical components.Ā 

Most entry level soldering irons will do the job, and your kit will come with more than enoughĀ solder.Ā Ā 

Be careful when soldering. Solder won’t melt until it reaches 185°C (365°F) and solderingĀ irons get very hot, up to 392°-896° F in some cases.Ā 

When soldering there are two key areas to keep in mind.Ā 

1. TinningĀ 

Tin your soldering iron and the components you are connecting to. Tinning refers toĀ maintaining a light coating of solder over the tip of your soldering iron and preventsĀ the iron tip from oxidizing.Ā 

2. PreheatingĀ 

Soldering is really about transferring heat. The lug or component you are connectingĀ to should be preheated so the solder is drawn to it rather than staying on the alreadyĀ hot iron.Ā 

WiringĀ 

Next we’ll connect the electronics. The STH does not come with the wiring pre-connected soĀ we’ll need to complete all the connections ourselves.Ā Ā 

As a basic overview, the pickups generate the initial signal which is then sent to the pickupĀ selector where the signal is switched to either neck or bridge position or a combination ofĀ both (middle position).Ā 

STH wiring

From here, the output from the pickup selector travels through the volume pot, and basedĀ on the position of the pot some of the signal is sent to ground reducing the overall voltageĀ and in turn reducing volume.Ā 

The tone pot based on it’s position will also direct some of this voltage through the capacitorĀ and high frequencies will pass through it (it works like a filter) and are sent to ground,Ā reducing some of the high frequencies. Finally, the ā€˜hot’ lug of the input jack is connectedĀ which allows the signal to be sent to the amplifier.Ā 

In the image above I am using a template to keep the various components stable. You couldĀ also use a set of helping hands.Ā Ā 

The wiring diagram below shows the completed wiring. We’ll work through each in a step byĀ step process below.Ā 

wiring diagram

Grounding the volume potĀ 

Our components must be grounded to limit electrical interference, namely 60 cycle humĀ from lights and household appliances. Single coil and P90 pickups are especially susceptibleĀ to this.Ā 

We’ll eventually connect all our components as part of a ground circuit and connect to theĀ ground wire we previously installed against the bridge bushing but first we need to groundĀ our volume pot.Ā 

grounding the volume pot

This can be done by either pulling the lug on the left of the potentiometer when facing awayĀ from you (ground lug) onto the case of the potentiometer and soldering into place, orĀ soldering a small wire from the ground lug to the back of the case.Ā 

Remember when soldering to ensure the tip of the soldering iron is tinned, along with theĀ lug you will be connecting to. Preheat the lug before adding a small amount of solder.Ā Ā 

Once the solder reaches melting point remove the iron and wait for the connection to cool.Ā Then, test the connection by gently pulling on the wires.Ā 

Connecting the capacitorĀ 

Next, we’ll connect the capacitor.Ā Ā 

connecting the capacitor

This is essentially a filter that passes high frequencies to ground allowing us to adjust ourĀ tone. We connect one end of the capacitor to the middle lug (the output lug) and the otherĀ end to the back of the case. Follow the method outlined above with regard to soldering, andĀ once complete trim any excess wire.Ā 

Installing the input jack wires

Next, taking one of the shorter wires in your packaging we’ll connect the ground wire to theĀ input jack (black is usually the color used for all ground wires).

installing the input jack wires

First thread the wire through the input jack hole and then thread the bare wire through theĀ eyelet of the ground lug (the lug connected to the inner sleeve of the jack) and make theĀ connection as we have done previously.Ā 

Connecting the ground circuitĀ 

Ā We’ll complete our ground circuit next, by connecting all of the components together in aĀ circuit and then connecting to the ground wire we installed earlier against the bridgeĀ bushing.

connecting the ground circuit

Now’s also a good time to also know the tone pot goes to the front of the cavity and theĀ volume to the back, so be sure to connect them in that order so they can be moved to theĀ electronics cavity without any problems.Ā 

The first connection we’ll make is connecting the volume and tone pot. Using a short piece ofĀ black wire, expose bare wires on both ends and then solder in place to the back of bothĀ cases, as per the image above.Ā 

Next we’ll install the ground wire we installed against the bridge post bushing earlier.

install the ground wire

Follow the same process as above and connect the ground wire to the back of the tone pot. ItĀ doesn’t matter which of the pots you connect to, but in this case the tone pot is the mostĀ accessible.Ā 

Next we’ll ground the pickup selector.Ā Ā 

grounding pickup selector

Connect another black wire from the back of the volume pot to the ground lug on the pickupĀ selector.Ā Ā 

This is the lug directly connected to the case of the selector switch and is the only lug on oneĀ of the sides (as per the image to the left).Ā 

Connecting the pickup wiresĀ 

Next we’ll connect the pickup wires to the pickup selector. This allows the bridge, neck or aĀ combination of both pickups to be output from the selector to the volume pot.Ā 

connecting the pickup wires

Connect the shielded ā€˜hot’ wire from the neck pickup to the top most lug, this is the lug thatĀ will be used for the neck pickup.Ā Ā 

Once complete, next, connect the unshielded bare wire to the back of the volume pot.Ā Ā 

connect unshielded bare wire

Do the same for the shielded and ground wires from the bridge pickup.Ā Ā 

In the image below I am making these connections from inside the control cavity as theĀ wires are too short to work outside the guitar.Ā 

connections inside control cavity

Connecting the output from the pickup selectorĀ 

Our third last connection is the output from our pickup selector. This is the wire that takesĀ the signal from the pickup selector (whether it is neck, bridge or a combination of bothĀ pickups) to the input lug of the volume pot (the lug on the right if facing away from you).Ā 

From the input lug of the volume pot it is then connected to the output lug of the tone pot.Ā It’s often easier to measure the length of the two wires and twist them together beforeĀ making just one connection at the volume pot, rather than trying to connect a secondĀ independent wire from the volume to the tone pot.Ā 

Connecting the input jack to the volume potĀ 

Just a couple of connections left to make now. Next we’ll connect our input jack to ourĀ volume pot.Ā  Ā 

connecting input jack to volume pot

Simply solder another white wire to theĀ ā€˜hot’ lug of the input jack as per theĀ 
image below.

solder another white wire

The color doesn’t necessarily matter,Ā but it will help you identify the wiresĀ 
more easily. Next, connect the otherĀ end of the wire you just installed to theĀ 
input jack to the output (middle lug) of the volume pot.Ā 

Once complete we’ll connect the ground from the input lug to the back of the volume orĀ tone pot. In the image above I am using the tone pot as this was easier for me to solder toĀ inside the control cavity, but it really won’t matter which you choose.Ā 

That completes your wiring. You can now test your wiring by plugging a cable into the inputĀ jack and connecting to an amp. If you don’t have strings on the guitar, simply tap eachĀ pickup while in their respective positions and ensure everything is working correctly.Ā 

If you hear interference which stops once you touch the guitar it’s likely there’s an issue withĀ your ground circuit.Ā 

4. Final SetupĀ 

The last stage of our project is setting up the guitar. This is an important step that makes allĀ the difference with regard to playability and tone. Our final setup will consist of four keyĀ areas:Ā 

I’ll provide a basic overview of each below. Also, keep in mind the guitar should be tuned toĀ concert pitch and checked regularly during the process to ensure the correct amount ofĀ tension is on the neck as adjustments are made.Ā Ā 

You may also want to revisit aspects of your setup once you have had time to play the guitarĀ and have identified problems e.g. fret buzz or intonation issues.Ā 

Adjusting neck reliefĀ 

The ideal guitar neck is one that has a small amount of inward bow or relief to provideĀ clearance for the strings when vibrating. A neck that is too straight will very likely run intoĀ problems with fret buzz.Ā 

You can measure the straightness of the neck using a steel ruler. I prefer to hold down theĀ first and last fret and then tap the 12th fret lightly of the low E string. If the string is alreadyĀ sitting hard against the fret more relief is required. If sitting well above the fret, the amountĀ of relief can be reduced.Ā 

measuring the straightness of the neck
To adjust the amount of relief, adjust theĀ truss rod using the hey key included inĀ 
your packaging.Ā Ā 

adjusting neck relief

Turn counter clockwise to loosen theĀ truss rod which will introduce moreĀ 
relief. Turn clockwise to flatten the neckĀ further.Ā 

Remember to only make incremental changes of ā…›th to a ¼ turn each time and make sureĀ the guitar is tuned to concert pitch so the correct amount of tension from the strings isĀ placed on the neck. Be sure to continue to check your tuning through the entire setupĀ process.Ā 

Adjusting the actionĀ 

Action refers to the height of the stringsĀ from the fretboard of the guitar. This isĀ 
usually measured from the top of theĀ 12th fret to the underside of the low EĀ  string.Ā

A good starting point if unsure is 2.4mmĀ on the low E side and 1.6mm on the highĀ E side, taking into account the differentĀ string gauges.

adjusting the action on the bridge

Make sure the guitar is in tune before checking and making adjustments. Action is adjustedĀ at the bridge. Loosen the bridge posts to raise the action, tighten the bridge posts to lowerĀ the action.Ā 

Intonating the guitarĀ 

Intonation, in essence means, is theĀ guitar in tune with itself. You can checkĀ 
this by tuning to standard tuning andĀ then checking the strings at the 12thĀ 
fret (an octave up from the openĀ string). If the pitch is sharp you willĀ 
need to lengthen the string length. IfĀ flat you will need to shorten it.Ā 

intonating the guitar

As mentioned earlier. Your scale lengthĀ is not a precise measurement as thereĀ 

is some compensation required for theĀ additional mass of the heavier bass strings. This is also why most bridges on electric guitarĀ are angled away from the body of the guitar toward the bass strings.Ā 

To lengthen the string, turn the intonation adjustment screws at the front of the bridgeĀ counter clockwise. To shorten turn them clockwise. Make sure the guitar is in tune beforeĀ checking and adjusting.

Adjusting pickup heightĀ 

Lastly, we’ll check and adjust the pickupĀ height.

Much like string action, the height ofĀ your pickups is mostly subjective andĀ will depend on what you are hearing.Ā  Ā 

But, if unsure a good starting point isĀ 2.4mm from the top of the magneticĀ pole piece to the underside of the string.Ā However, this should be measured when pressing down the last fret of the guitar.Ā 

adjusting pickup heights
To adjust the height of the pickups, adjust the mounting screws on the outside of the pickupĀ surround.Ā 

SummaryĀ 

And that marks the end of our project.Ā 

Once you have completed the steps outlined above. You should have a complete guitarĀ ready to play. Keep in mind, as you become more accustomed to the guitar you may want toĀ revisit some aspects, especially the final setup of the guitar.Ā Ā 

You should also test the guitar, by going through each pickup position and testing theĀ volume and tone pot. Also test for interference by taking your hands off the guitar andĀ listening for hum. If you hear any signs of electrical interference you may need to open theĀ electronics cavity and check your ground circuit.Ā 

Lastly I’d recommend playing each fret up and down each string and listening for fret buzz orĀ any sign of dead notes. If you notice a problem, chances are it can be resolved by eitherĀ adjusting your action or adjusting your neck relief.Ā 

Thanks for following along!Ā
