treble cut switch needed

[RandomGlitch]

Hi,

Ive built myself a fuzz pedal to which I've incorporated a modified big muff tone stack.  It sounds just great.

However, what I want to sometimes, for some songs, is simply roll off some of the high treble.  If I adjust the tone stack to reduce the treble, it kind of changes the whole tone, which I don't really want.

I was hoping to do something like have a capacitor (+ resistor??) that I could switch in to give a pre-defined high end cut (in addition to the tonestack shaping).

Can anyone suggest how this might be done and what component values I need?

Thanks!!!

Look at the Trotsky drive at beavisaudio.com, I think it has what you need.

Perfect! Thanks very much Perrow.
