Ultimate 40 combination wiring?

Hi there

As you’ll see from my activity I’ve not been on here posting for a very long time, however this forum has always been a fantastic resource for the budding modder and I’ve always found the advice from the knowledgeable regular posters to be invaluable.

With that in mind I thought I’d share my current plans for a guitar I’ve working on at the moment. It has space for 3 pots and 4 mini switches, with no space for strat/tele/Gibson style levers. It has stock pickups of HSS.

I’m looking to put as many options into the guitar as possible. Partly for fun, partly curiosity, partly to create a “pick up and go” guitar for when I’m late to rehearsal and don’t have time to pack up pedalboards and main guitars.

I’ve also got a treble booster circuit and an N-Tune onboard tuner I’m planning on putting in there.

So I’ve attached the image below which shows what I’m trying to achieve, and the wiring that I think will achieve it.

I guess I’ve got two questions before I order all the parts and get out the soldering iron:

1. What have I done wrong, where have I made some rookie mistake in my wiring diagram, maybe creating a load of unwanted hum or some surprise off positions (there should be two of those!)
2. Any thoughts on the wiring itself or things you’d change if it were you?

I calculate this gives 40 unique pickup combinations plus 2 ways to kill the sound, as well as the various volume and 2 band tone controls, plus tuner and treble booster. Not the most convenient guitar to borrow but should be some fun to piece together and play!

Thanks everyone
 
Re: Ultimate 40 combination wiring?

I've just noticed the quality of the picture is a bit pixelated. I think the diagrams are readable, the tope part says the following:

Wiring diagram for Humbucker switchable between series, parallel and off, middle and neck single coils switchable between in phase, out of phase and off, master series/parallel switch for how pickups interact with each other, master tone treble roll off, master tone bass roll off, master volume, outputted either direct to guitar output, or with added treble booster powered by PP3 battery between volume and output jack, or muted and sent to onboard tuner powered by same PP3 battery
 
Re: Ultimate 40 combination wiring?

It's really difficult to analyze someone else's diagram. Especially when non-standard symbology is used. But one problem jumps out: it appears that the 4PDT on-on switch, in the upper right corner, has the right side of the switch connecting the "from neck" wire to "treble tone" in either position. Why even use the switch. Just connect the neck wire to the tone control. Secondly, it's hard to analyze anything beyond that without knowing what "from pickup" and "to pickup" mean. Are those hot wires? Ground wires?

This will be very difficult for anyone to troubleshoot, but there are problems. :)

Thanks Artie

Ok that makes sense. What I’ll do is draw it up in a way which should make a bit more sense to follow and will post that.

Cheers

Hopefully the attached makes a bit more sense. I've not used standard colours as hoped that by using multicoloured it would make following the wires easier.

Any input or thoughts would be greatly appreciated.

Thanks

(BTW the DPDTs are on-on-on)
 
Re: Ultimate 40 combination wiring?

I've come to the conclusion the bridge switch to turn on in series, off and on in parallel, using an on-on-on switch is not going to work, so have changed to on, off, split (again using an on-on-on dpdt). See below, any comments or thoughts welcome:

Re: Ultimate 40 combination wiring?

Apologies for yet another version, previous had battery incorrectly wired. This is hopefully now all in order:
