CUSTOMER NOTICE - I am closed between Friday 1st March and Monday 4th March due to exhibiting at The Guitar Show 2024. No online orders will be processed/handled until my return to 'normality!' on Tuesday 5th March. Thank you very much for your kind interest, support and patience through this busy show weekend.

Pre-Wired Guitar wiring harness | Jazzmaster 'Lead' Circuit kit | Right Handed

£62.49

Order times
I usually make harnesses to order, due to the variety of spec options that could be chosen across the whole range. The current turnaround time for a harness orders is around 5-7 working days depending on quantity of orders in at the time and your order will be updated accordingly when it is dispatched. This turnaround time doesn't include the transit time. Thanks for your patience whilst I get your harness made!

Description
It's no secret that I love Jazzmasters. From the comfort of the offset body shape, to the intuitive trem and ultimately, the sound. So this harness was definitely driven by the passion I have for the Jazzmaster design. 
This particular harness is for a lead circuit only 'conversion' so to speak. So this harness is wired as if the rhythm circuit didn't exist, and is a standalone lead circuit. So it is great for those who wish to remove the rhythm circuit from their guitar, perhaps building a JM partscaster and don't wish to fit a rhythm circuit, or perhaps are planning a build based around non JM single coils, with humbuckers instead perhaps. I offer it with a choice of traditional 1 Meg pots, 500k pots, or 250k depending on your preference or pickups you plan to use. and now also offer it with the choice of .022uF(great if it's a humbucker or P90 configuration) and the traditional JM lead circuit .033uF if you'd like to stick with the traditional spec and JM single coils, and finally .047uF if you want a little bit more pronounced top end reduction/control or have a set of pickups that would benefit from this spec/maker recommends to use.

If you have any questions about specs, feel free to drop me a message, happy to help where possible!

Installing
I have intended for my wiring harnesses to be as simple as possible to install to your Jazzmaster, as well as writing in depth fitting guides, how-to instructions documenting the step by step process as well as a simple to follow wiring diagram.
The parts I use, in particular the pots, are CTS branded pots which are imperial measurements. If you're fitting this harness to a far east built variant for example such as a Squier or similar, then you may have to widen the holes in the control plate to accommodate for these imperial measurement pots. Or alternatively, purchase a new control plate that is already suited to the US spec components. 
For reference, the CTS pots I use in this harness have a shaft diameter of 9.52mm.
You may also require new control knobs to fit the CTS pot 'split shaft' spline diameter of 5.95mm.
If you do require a US spec control plate or control knobs, we do carry a selection of popular options in stock and they can be viewed in the hardware & plastic hardware categories on the store.

The mounting board I ship my harnesses out on, were taken from measurements of a USA built Fender Jazzmaster. The centre to centre measurements between components are - 
Centre of 3 way toggle switch to master volume pot - 11.5cm
Centre of master volume pot to master tone pot - 5.2cm
Centre of master tone pot to jack socket - 6cm


Specs
- CTS '450' Series +/-10% Tolerance short shaft pots - 250k split or solid shaft
- CTS '450' Series +/-10% Tolerance short shaft pots - 500k split or solid shaft
- CTS '450' Series +/-20% Tolerance short shaft pots - 1 Meg split or solid shaft
- 'Yellow Mustard' type tone capacitor 
- Gavitt USA made cloth covered 22AWG wire
- 20AWG Tinned copper ground
- Switchcraft right angle 3 way toggle switch
- Pure Tone multi contact jack socket
- 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 nut.

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.
