So I think I've gotten an understanding of how the Wal preamp works, and I'd like to make one for my Herrick multi-coil pickup. However in order to implement the resonant filter + 10 dB Q boost, I'll need a liner dual gang push-pull (DPDT) potentiometer. But I'm beginning to realize how rare they are - do ya'll know if this is something I have to get custom made or do you know of any distributors that sell them?
I'm in the US btw.
