Farfisa Wha-Wha/Volume
Hi,
a friend gave me a Farfisa Wha-Wha/Volume pedal. The battery leaked (probably some decades ago) and destroyed part of the backplate.
I replaced the battery snap, checked the wires and now it seems intact. But so far I just got a really really quiet sound out of it.
Does anybody has a schematic or some informations about it?
It seems to be the predecessor of the Maestro Wah-Wah/Volume Pedal but I didn't found a schematic.
Those Maestro Pedals seem to acquire high prices on ebay, but the only Farfisa unit I found was sold for some bucks.
'Really glad if somebody could help me.

So you have this pedal.... not working.... but yo have the pedal.
Why don´t you take some pictures from the inside, the component side of the pcb and the track side of the pcb and post it here ? Maybe someone will trace it and draw a schematic.... But without any pictures your chances ar much worse.

Nice..... but I can´t see a track/solder side .... which is important for tracing....

Ok. I took some photos and tried to trace it.
Looks like a simple wah circuit to me.
I'm not sure what the correct values of the three capacitors are.
The pot is a dual pot, but so far I don't know the specs.
The 560K resistor looks a little bit suspicious.
Unfortunately I can't upload files here at the moment, so here are the imgur links:
