microswitch ON/OFF/ON PB bass guitar

Postby lawarmotte » Tue Jan 19, 2021 1:45 pm

Hi there !

I'm a newbie speaking of guitar wiring, so I need some advice :thumbup:

I made some modification on my PB bass, so it was suppose to work that way:
- Not pot, direct wiring
- Just a 3 positions micro switch

Position 1 for direct sound out of Pickup
Position 2 (middle) OFF position
Position 3 Clean sound with capacitor

Everything is working fine, except that both up & down positions have the same sound :madas:

So... I don't know what I've done wrong, so thanks in advance for your help !

Yes, they would! It's because both sides of the switch are joined directly together.

There are several ways you could do this, but one of the simplest would be to wire the output socket from the two switch wipers (middle contacts) , and loop the pickup across the two outside contacts, with the tone capacitor across one side like this:

Or as a schematic:

So one side of the toggle switch is selecting the pickups in both outer positions (and mute in the middle), while the other side is used to strap the capacitor across the output only in the bottom position.
