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 | J-Bass kit | Right Handed

£41.66

Order time
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!

Model Description
The introduction of my harness for Jazz Bass was to compliment the models of McNelly J Bass pickups that I also offer, and I wanted a quality upgrade for your wiring that would work well with those great pickups. It's a simple recipe of the highest quality components to bring the best out in your bass. As standard I offer this harness with the traditionally used 250k pot rating and features the traditional spec of individual volume control for each pickup and a master tone control.

Options

Control plate or pickguard mount?
If you are mounting this wiring to a traditional metal control plate, then please select this option via the drop down menu. For this mounting style, I will not add an additional ground bus wire between each pot and jack as there will be sufficient ground continuity via the pot casings/jack sleeve upon mounting them to the metal plate.
If you have a slightly different Jazz bass, perhaps a modded one or one with a full plastic pickguard where the pots and jack mount through plastic instead, please select this option via the drop down menu. For this mounting style, I will pre-solder additional ground bus wires between each pot and jack and that wire will provide sufficient ground continuity via the pot casings/jack sleeve for you. 
This option will ensure sufficient ground connection for your style of Jazz bass, and also ensure there is no risk of a ground loop. 
Not sure what you'll need? Drop me an e-mail and I'll be happy to help guide this choice :) 

Pot shaft type
This option ultimately comes down to what type of control knobs you are planning to fit. Traditionally Jazz Basses have solid shaft pots with grub screw fixed control knobs, so if you have those and they're suited to 6.35mm solid shaft diameter pots then choose the solid shaft pot type.
If you fancy mixing things up a bit and want some other styles of control knob such as push-fit type. Then you will need split shaft pots and control knobs that suit a 5.95mm(adjustable) 24 spline pot.

Capacitor value
This may come down to personal tastes in terms of tone and tone control response, what your pickup maker recommends or what period of Jazz Bass you have/are trying to replicate. .022uF I would consider as a great all round spec, nice roll off of the treble frequencies through the tone control sweep and a little more top end left over. I consider this the more 'modern' spec and can be seen on many current day production models. The .047uF cap spec has a slightly more drastic roll off of the trebles and warmer tone overall, and this was also the spec used on vintage Jazz Basses if that is the sound you're hoping to replicate.

Fitting notes

I have intended for my wiring harnesses to be as simple as possible to install to your J-Bass, 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. But here are some important spec and fitting notes that will hopefully help you assess whether the kit is suitable for your bass guitar or what is required to allow it to fit correctly.

Will the pots fit my control 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 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. The CTS pots have a mounting thread shaft diameter of 0.370" / 9.4mm so I recommend for ease of install a control plate with a 0.394" / 10mm pot mounting hole.
The jack socket I use in this kit again is imperial specification, the outer thread diameter measures 0.367" / 9.32mm and ideally requires a 0.394" / 10mm hole to comfortably mount.


Centre to centre measurements between components are - 
Centre of Volume pot 1 to centre of volume pot 2 - 35mm
Centre of Volume pot 2 to centre of tone pot - 35mm
Centre of tone pot to centre of jack socket - 35mm
These measurements for my templates were taken from a USA Fender J-Bass control plate. There is a small amount of 'give' in the wire lengths between the components, but if for any reason the measurements on your bass are drastically different to those stated above, please do get in touch and I may be able to make your kit with an allowance for this. You will need to provide your centre to centre measurements to me. 

What control knobs will fit?
The CTS Solid shaft pots option have a solid shaft diameter of 0.248" / 6.30mm. You will need control knobs that suit these measurements and secure to the pot via a grub screw on the control knob.
The CTS Split shaft pots option have an adjustable split shaft diameter of 5.95mm with 24 'splines' and will need control knobs that suit these measurements and secure to the pot via push-fit.
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 need suitable control knobs, please see the guitar parts section of my site. 

Parts used/included
- CTS '450' Series +/-10% Tolerance pots - 250k, solid shaft
- .022uF 'Yellow Mustard' type tone capacitor 
- Gavitt USA made cloth covered 22AWG wire
- 20AWG Tinned copper ground
- 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/control plate etc but does include the pot/jack mounting nuts and washers.

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.
