Pretty nifty idea with the two levers, and cheaper/ easier to make than the rack and pinion solution often seen.

Sticking in a bridged-T like that, switchable, might make a cool mod for a fuzz face (being as that is what this is, pretty much).

Hi Jarno,

Another easy way to rotate a wah potentiometer was implemented by Ernie Ball: one spring, a couple of bushings, several inches of wire and a little pulley at the pot shaft:

This solution, with a little experimentation, allows for a complete rotation of the potentiometer. 8)
cheers,
Jose

I have an Ernie Ball volume pedal, so I am familiar with that mechanism, but with the rope and the spring, it might be a bit finicky to DIY this and get it right. Interesting assembly manual, might need to replace the cord on mine at some point in time (didn't buy the pedal new :) ).
