This is really cool. Thanks for sharing.

Any thoughts on a matrix switcher that would allow you to change the order of the effects in different patches?

It was the caps. Replacing with C0G and tantalum caps fixed it.

C0G/NP0 mostly but I think the caps may not be the case here Any ideas? Fumbling with DC cables or input cable produces microphonic effect. Eliminating the pedal and the rest of the board is quiet. Isolating it (using just this pedal) into amp is producing it. So then I opened it up and started cho...

These are 1206 SMD XR7 ceramics, so yeah, I may have replaced microphonic caps with more microphonic caps. :) But there is a big 220uF electrolytic in front of them that I'll replace next. It has a good ESR, but I'll change it out anyway. If that doesn't do it, should I look into C0G caps for the SM...

Guessing this should've gone in the Request folder. Apologies. I'm new here.

I have an MXR M109 6 band eq pedal that appears to be microphonic. After poking around with a chopstick, it appeared that C2, C3, and C4 were all making noise. I traced the board out and, other than the addition of a switch and extra filtering, it is the same basic design as the old M109 schematics ...
