Osiris Posted June 18, 2018 Posted June 18, 2018 I've just acquired a Fender Mustang P/J. The control layout is master volume and tone knobs with a 3 way pickup selector switch. As I only ever leave passive tone controls fully open, I want to know if it is possible to rewire the bass so that it can have a pickup blend pot instead of the tone? For me, a blend pot would be far more useful than the tone control. The little metal control plate only has holes for 2 knobs and I don't want to go at it with a drill to make room for a third pot. Ideally I can just swap the tone for a blend and not have a tone control at all. If it is possible to do, would there still need to be a capacitor wired into the circuit somewhere? I seem to recall having a passive bass rewired years ago to bypass the tone control and there was excessive top end in the signal, and I seem to think at the time that I was told that it was because there was no capacitor (possibly the tone pot too) in the signal and that these naturally remove these ultra-high frequencies from the signal. The pickup selector switch can be left in place but not wired in. Can it be done? Does anyone have a suitable wiring diagram? Are there any reasons why it would be a bad idea? Quote
KiOgon Posted June 18, 2018 Posted June 18, 2018 Try the diagram below, just leave out the tone pot and cap. https://www.seymourduncan.com/wiring-diagrams?meta_params=bass-options,2-pickups,neck-pb,bridge-jb,1-volume The difference between leaving the pot and cap out or having them in with the pot wide open is impossible to detect with 'normal ears'. If you don't like it you can soon drop a cap in to tame the top end. Cheerz, John 1 Quote
Thunderbird Posted June 18, 2018 Posted June 18, 2018 Thats the one I found that diagram online and thought that would be the way to go Quote
Osiris Posted June 18, 2018 Author Posted June 18, 2018 Thanks @KiOgon. What would the best thing to do with the wires that are all soldered to the back of the tone pot in that diagram? Can they be soldered to the back of the volume? Does that make sense to you @Thunderbird seeing as you'll be wiring it up for me Quote
