Model Description

I have spent my guitar playing life around Stratocasters. I first become interested in them at the age of 5, seeing the likes of Hendrix, Clapton, SRV and Gilmour playing them on concert VHS tapes that my parents would put on whilst growing up. Although I was young, I soon noticed that all these people were playing the same type of guitar, and that really caught my eye. On my 6th birthday I asked for a guitar, and was incredibly lucky enough to have received a Squier Strat, and the Strat in general was pretty much all I played right up until my 30s. So needless to say, the Strat harness range is close to my heart and something I wanted to ensure is the best quality product I could offer to help bring out the best in your Strat too. 

This is the 'EJ' (Eric Johnson) inspired harness which I have decided to now offer alongside other strat models as I feel it differs enough to justify the variation of model. 
I was recently honoured to work on and have a close look at a Dale Wilson Master Built Stratocaster, and had my first 'hands on' experience of this wiring style which delivered interesting results.
A quick look at the originals and back when the strat was introduced, it was popular for electric guitars to have a ‘lead’ position, something that would cut through in big bands and soar for solos. Or perhaps to help bring some clarity from some of the darker sounding amps available to most players at the time. Let’s also not forget that at the time, much bigger gauges of strings were more commonly used and in a lot of examples too, flatwounds. So a lot of reasons as to why manufacturers made sure their models had a bright 'lead' tone. I certainly think it’s pretty safe to say this may have been one of the reasons why when Leo released the Strat, It originally only featured 2 tone controls (one for neck pickup, one for the middle pickup and usually a 0.1uF cap) whereas the bridge pickup’s signal didn’t pass through a tone pot or cap, only the volume pot’s resistance was effecting it’s signal. Resulting in a bright, cutting, and bold ‘lead’ position. 
Now, this 'EJ' inspired circuit is similar to the details noted above, but instead of the bridge pickup having no tone control, it is actually the middle pickup instead. So to summarise, neck pickup has a tone control (1st) then the bridge pickup has a tone control (2nd pot) but the middle does not have a tone control which aside from giving the middle position a more pronounced tone, it alters how the 'in-between' 2nd and 4th positions sound too. Perhaps a reason in particular why EJ opts for this spec over others in his signature model Strat.

This specific kit is for the left handed orientation version of my EJ Strat harness. 

In summary -

Master Volume control
Tone 1 - Neck pickup adjustment only
Tone 2 - Bridge pickup adjustment

Switching
Position 1 - Bridge pickup with with volume and tone adjustment
Position 2 - Bridge pickup with middle pickup in parallel with volume and tone adjustment
Position 3 - Middle pickup with volume only
Position 4 - Middle pickup with neck pickup in parallel with volume and tone adjustment
Position 5 - Neck pickup with volume and tone adjustment

Product options

Pot taper
I offer my left handed orientation pre-wired kits with the choice of pot taper spec. Regular right handed audio taper pots (clockwise rotation direction to increase from 0 to 10), or with reverse/left handed audio taper pots (anti-clockwise rotation direction to increase from 0 to 10). Which you select ultimatly comes down to which spec you personally prefer to use. I have found from the years of offering these kits, researching the specs and speaking with many left handed players, that these preferences most definitely vary. This most likely is a result of inconsistencies between guitar brands, in how they wire guitars. Therefore a player might get used to using their pots a specific turn direction. 
As a result, I wanted to offer the choice of which pot spec you can order your kit to be made with. If you like your pots to turn clockwise from 0 to 10, then select right handed audio taper pots, whereas if you prefer your pots to turn anti-clockwise from 0 to 10, then select reverse/left handed audio taper pots. I hope this helps

Tone cap value
I am always open to changing cap values across my harness range on request, but as this schematic is a bit more user specific I have decided to offer cap value choice as a drop down option. If you are looking for true 'EJ' specs then you'll need a 0.1uF value tone cap.
If you would find that cap value a bit too dark/warm sounding, and want something a little brighter then you may prefer to more modern values of .047uF or .022uF. The latter will be the 'brightest' response.

Bridge/vibrato claw ground wire
I have decided to make this option available, as many of you may be using this wiring kit on a new, partscaster type build for example. If you are fitting this kit into your existing guitar, and re-attaching the guitars original bridge (hardtail strats) or vibrato claw (vibrato equipped strats) ground wire then simply select without. If you have had to remove the original perhaps, or it’s for a new build altogether and would find having a ground wire pre soldered, simple select with! I supply a 1ft length of Gavitt 22awg wire. Hope this option helps with your specific project.

Fitting information

I have intended for my wiring harnesses to be as simple as possible to install to your Stratocaster, as well as writing in depth general fitting guides and simple to follow wiring diagrams for each wiring style. There are also multiple useful how-to guides regarding wiring work found HERE too. But in this section you'll find some important fitting notes that will hopefully help you assess whether the kit is suitable for your exact Strat or what is required to allow it to fit correctly.

Can I fit this kit myself?
This ultimately comes down to whether you own the equipment needed to correctly and safely install the kit, or how comfortable you feel working on your own guitar. I do feel that installing a pre-wired guitar harness is do-able for many guitarists but only if the correct tools are used and care is taken to ensure you do not damage the kit, your guitar or yourself! There are detailed installation guides here on my website, as well as simple to follow wiring diagrams all to help make the process as easy as possible and in my experience, these have helped thousands of my customers carry out their own install. But if for any reason you have concerns about fitting the kit yourself which is entirely understandable, then I'm sure you'll agree that it is likely best to have a professional fit the kit and help ensure your purchased kit, and your beloved guitar are both looked after and worked on correctly. 
If you are local to me (Stourbridge, West Midlands) I take on guitar work no problem at all so will certainly be able to help install your Signature Series harness. 

Will the pots/jack fit my pickguard and jack plate?
The components I use in my Signature Series wiring kits are for the most part, USA imperial specification. If you're fitting this harness to a far east built guitar such as a Squier or similar brand, then you may have to widen the holes in the pickguard to accommodate for these imperial measurement pots. Or alternatively, purchase a new pickguard that is already suited to the US spec components. The CTS pots and Pure Tone multi contact jack have a mounting thread shaft diameter of 0.369" / 9.38mm so I recommend for ease of install a pickguard and/or jackplate with 0.394" / 10mm pot/jack mounting holes. You can easily widen the holes in the Pickguard too if you would prefer, I recommend doing this safely with a step cutter drill bit. I also offer this as a service so if you would like me to widen your plate for you, do please get in touch and we can organise this additionally.

If you’re buying this kit for a USA or Mexican made Strat, then chances are it will be a direct, no modifications install process for you. 

Centre to centre measurements between components are - 
Centre of Switch to volume pot - 48mm
Centre of volume pot to centre of tone pot 1 - 45mm
Centre of tone pot 1 to tone pot 2 - 45mm
These measurements for my mounting boards/templates were taken from a USA Fender Stratocaster pickguard. Yours may vary from these measurements. If it is a minimal difference, then don’t worry. I allow for some ‘wiggle’ room in the wire lengths between components to help the product fit a wide variety of models. If the measurements are drastically different to these, then please get in touch with your centre to centre measurements and I will adjust to suit your instrument more closely. 

What control knobs will fit?
The kit uses CTS Split shaft pots which have a adjustable split shaft diameter of 5.95mm w/ 24 splines. You will need control knobs that suit these measurements.
Do not attempt to force fit smaller, metric/import spec control knobs onto the imperial USA spec pots, doing this can damage the pot.

If you do require a US spec control knobs, I do carry a selection of popular options in stock and they can be viewed in the Control Knob category on the store.

Which switch tip will fit?
Much like with the control knobs, the CRL switch used in this kit is USA spec, with imperial sizes. Therefore you need a switch tip which will fit a CRL switch, which measures 0.185" / 4.72mm

If you do require a US spec switch tip, I do carry a selection of popular options in stock and they can be viewed in the Switch Tips category on the store.

Specs/Parts included

- 3x CTS short shaft pot - 250k split shaft (left handed or right handed audio taper depending on spec chosen)
- 1x 'Yellow Mustard' type tone capacitor
- 1x Pure Tone multi contact jack socket (nickel finish)
- 1x CRL spring loaded 5 way lever switch
- Gavitt USA made cloth covered 22AWG wire
- 20AWG Tinned copper ground
- Soldered using R-Tech Premium Lead-Free (Sn95.5Ag3.9Cu0.6) 22swg Solder wire 
RoHS Compliant

Please note - wiring kit does not include new control knobs/switch tip/control plate etc but does include the pot/jack mounting nuts and washers and switch mounting screws.


Why these spec parts over others available?
Simply put, component choice has been one of the most important parts of my product development. I have worked on guitars for many years, and built these kits professionally since 2015, and as a result have been able to see and experience working on the majority of components available on the market. In my findings, A/B testing and more, I have found the components I decided on for my Signature Series to be the most reliable, best tolerance and great functioning parts to use to help customers get the most out of their instruments. I use CTS '450' series premium spec pots as they have a tight tolerance, and will consistently provide me with accurate value, as well as very solid build quality. I use trusty 'Mustard' style polyester film 'tone' capacitors as in my opinion they simply can't be beat for great value, solid construction, solid lead-outs, super tight tolerances and reliable tone/function. I would personally much rather use a trusty Mustard for example over something like a paper in oil, as from experience that are so much more reliable to use. This is from carrying out a lot of A/B testing, both tonally, as well as armed with the multi-meter for testing values and actual tolerances, as well as handling them to test construction quality for long lasting reliability in use. I use the brilliant 'Pure Tone' Multi Contact Jack sockets as they are incredibly reliable, due to their additional contact points for both tip and sleeve. I use CRL, Oak and Switchcraft brand switches across the range as these are built very well, with care will last for many years to come and have long since provided me with reliable use professionally. All kits are wired up with quality USA made Gavitt wire, it's great to work with, super consistent gauge and provides me with a very reliable quality item for my kits. I totally understand that with anything guitar, it is subjective, but I have, with an open mind, thoroughly tested a broad variety of components over the years and these have all become the items I trust to use every day. 

Harness FAQ's

I've been proudly making, developing and installing my pre-wired guitar harnesses since the beginning of the Home of Tone back in 2015 (time flies when you're having fun right!). Although I feel I do my best in covering as much information as possible across the various product listings, fitting guides, wiring diagrams and more, I thought it might be helpful to put together an FAQ's page that covers some of the general additional questions I get asked. You can view these Harness FAQ's HERE

'Ground Bug' deal!

Looking forward to installing your new wiring, but a little worried about making the ground connections to the pot casings? First time soldering and hear the horror stories of frying pots, or just simply want to neaten up your installs? Then the awesome 'Ground Bug' will help with any of these concerns, beginner or pro modders alike. The Ground Bug is a pot washer that fits between the pot casing and the pickguard/body and has a number of lugs (much like with the main signal connections on the pot for example) to which you can very easily solder your ground wire connections too. Completely removing the worry and risk of soldering a pot casing, something I know many guitarists complain about having to learn to do. 
I have been stocking Ground Bugs for a while, and they really are the perfect match for a pre-wired harness as they further help you with your installs. So I have set up a 10% off Ground Bug deals when purchased with a Home of Tone Signature Series pre-wired harness. This is an automatic discount code, so all you need to have is a Signature Series kit, and a Ground bug in your cart, and the discount will automatically be applied to the bug for you! Click HERE to view the Ground Bug listing

Do you make custom harnesses?

I'm afraid I do not offer a custom harness service. Only kits developed, tested and listed on my website are the available kits. So no custom schematics etc. If you happen to be local to my office, then I do carry out custom work in house, but in regards to shipped out pre-wired harnesses I do not offer custom kits. I am however happy to use different pot values or cap values within reason if you have a specific requirement that differs to the specs listed above. If this is relevant to yourself then please get in touch to discuss further to ensure the request is possible.
