Fuzz mods (expression/boost)

[rangermaster]

Hi

I would like to build a fuzz pedal with these features:

1. Option for expression pedal to control the fuzz
2. Second footswitch for Mid boost
3. A pot to control the mid boost
4. A switch to choose for the mid boost or treble boost

So how do i wire it so an expression pedal can be used? Just a extra jack on the fuzz fuzz pot?
And what to do so i can make a mid and treble option that can be switch on/off with a extra footswitch and the mid/treble can be switch by a dpdt switch.

I'm planning on making a fuzz face type pedal. So that should be the schematic i will use.

Thanks!

buy a cheap passive volume pedal, they are like 20 euros or so, and work like turning down the volume on your guitar, so with a fuzz face it cleans up beautifully. having a separate pedal is also convenient if you want to use it with/in front of another pedal.

as for that midrange control, do you want some active opamp circuit? do you want the depth to be controlled by the pot, or the frequency? does it have to be a net boost? can it be a boost in one place and a cut in another, to give the midrange another character?

cheers
