I'm building a guitar, and I'll have 2 pushpulls, one master tone, one master vol. The question is, what do I do with the push pulls? I'll already have switches for series, splitting, parallel, phasing etc.

kill switch? (worth it?)
different tone caps?
- high pass
- low pass
- anyone know how to make a mid-cut?
diode clipping? (probably not)
anything else I can do?


But yeah, I'm really interested in a mid cut filter, how do I do it?

for the mid cut filter, i'd probably make a high pass filter + low pass filter in parallel? lol iono but worth a plan.

and i love how u have so many switches already then u got a push/pull lol.

awesome! but what does the inductor do? And what value (in henries) do I need? Do I need an inductor? do these even sound good?

Anything else I can make out of a push pull?

Well I've played with inductors in passive circuits, and they don't seem to do anything. I know you need them for wah effects and stuff, but are they important here? I mean, you can easily build high pass + low pass filters without inductors, and couldn't you just put 2 in parallel?

Is there anything else I can passively do?

i think mid cut is more funner. mostly for the stevie ray vaughan tone freaks.

it is still passive. no LEDs just two DPDT push pulls.a/b/y switch.

As far as I know, inductors are like the opposite of capacitors. They resist treble more than bass frequencies.

A/B/Y would be for your outputs. You could have two- one is A, one is B (controlled by one DPDT), then Y is both of them (controlled by the second DPDT).

Ok, so I know what I want.

I want to have a mid cut, high/low cut, and a normal low pass. Has anyone had much success with passive bandpass or notch filters? I've been playing with some on a bread board, but I guess I can't choose appropriate values because it's not doing great. thoughts?
