capacitors

[JMPGuitars]

I have access to a laser engraver at the school that my wife works at, she works as the supplies and equipment coordinator in the tech studies area which can be useful at times.

You're lucky. I want to buy something like that, but they're insanely expensive for anything good.

Look at the tweaker's table. C7 is optional. So I put an on-off-on DPDT switch that includes a 500pF (C7) cap on one side, and an 82k resistor on the other.

For reverb I've built many of these with the "single valve reverb" method, though my current version is modified. The standard way sounds great though.

Thanks,
Josh
