3PDT charge pump question

[edgyswingsetacid]

I’d like to put one of these into a fuzz foundry deluxe build I’m about to get started on and I was wondering if someone could tell me if it’s compatible with that circuit and what kind of switch I will need to make it switchable?

If you have an 18V power supply or can hook up two 9V batteries, you might want to try that first. The Fuzz Foundry is all about biasing and increasing the power supply voltage will alter the biasing significantly. The GATE, STAB & COMP controls may or may not work correctly or their operating ranges will be shifted significantly. ZVEX says nothing in their instructions about 18V operation. What do you hope to achieve with higher voltage?

I was really just hoping to add the ability to switch to see what it sounds like but what you’re saying makes perfect sense and is plenty of reason to leave it out on this one. Thank you!
