Harness & Pickup deal set - The McNelly Broncomaster pickup is currently on made to order basis, and the currently McNelly leadtime is 5-6 weeks from time of order. Please note this if you place a full kit order.


Model Description
I am a big fan of short scale basses, and the Musicmaster is one of the best!, So I looked at creating a 'drop-in' wiring harness upgrade, using the high quality components I use on my other harnesses such as CTS 450 Series 'SSSP' pots, Pure Tone multi contact jack, Gavitt wire and vintage style yellow mustard tone capacitor. 

This, along with the optional McNelly Pickups replacement pickup, specifically designed for Broncos and Musicmasters turns this bass into a serious tonal instrument.

Options

With or without McNelly Broncomaster bass pickup?
I offer this pre-wired loom/harness kit as a complete upgrade alongside a pre-wired McNelly Broncomaster bass pickup. This pickup was designed by Tim McNelly specifically for the Bronco and Musicmaster bass, it features a true bass pickup design and has a great double pole piece design and hotter output for a full tone. Full description and demo video for this pickup can be found HERE. If you would like to order my wiring kit pre-wired to a McNelly Broncomaster pickup, select it via the drop down menu. If you don't wish to have the pickup and simply want the wiring kit/harness, then you can certainly do so here too. Lead times for each option chosen can be found right at the top of this product listing.
If you choose the pickup additionally, you are given the choice of a white, or black pickup cover. If you are just ordering the wiring harness, this option is not relevant.

Which pot shafts do I need?
For this kit I offer the choice of what spec of pot shaft you require. This ultimately comes down to what control knobs you plan to use on the bass. Split shaft pots use push-fit control knobs whereas solid shaft pots require control knobs that fix to the pot via a grub screw. Both are a different size and measurements are detailed below.
Useful tip - If you haven't decided what style of control knobs you are going to use, and can't make up your mind yet, I would recommend choosing the split shaft version as I also offer brass conversion sleeves which would convert split shaft to solid shaft pots with ease. So best recommendation if you're not sure, go for split shaft as they can always be converted easily, whereas with solid shaft pots you are tied to that as the only choice.

If you do require US spec control knobs, we do carry a selection of popular options in stock and they can be viewed in the control knob categories on the store.

Fitting notes

I have intended for my wiring harnesses to be as simple as possible to install to your Musicmaster 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 and what is required to allow it to fit correctly.

Will the pots fit my pickguard?
The components I use in my Signature Series wiring kits are for the most part, USA imperial specification. So depending on where your musicmaster was manufactured will be the deciding factor on whether the pots will be a direct fit, or the pickguard will need modification to fit. Or alternatively, purchase a new pickguard 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 to centre of tone pot - 41mm
Centre of tone pot to centre of jack socket - 34mm
These measurements were taken from a Genuine Fender pickguard, but I do allow for 'give' in the wire lengths between components to allow for small differences so there is some wiggle room for installation, it's not a 'fixed' measurement by any means. If these measurements are massively different to your guitar, just let me know the precise centre to centre measurements on yours and I will make it to suit that no problem at all.

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.
