I recently bought a Snarling Dogs Whine-O Wah and it's absolutely amazing. It's the best sounding Wah I ever tried.
But it's really really noisy!
So I replaced all the resistors (with metal film) and the caps with better ones, but no appreciable result.
Next step is to eliminate the extremly loud (probably LED caused) pop-noise.

I love this wah, but I also hate it. It's soooo noisy!! :cry:
Does somebody has ideas for troubleshooting or a solution :D ??

Ladies and gentlemen, let me introduce you the long awaited reverse of what some consider as the best chorus ever made.
It's taken from an original 80's version. I can't tel if the actually made SCF is the same or if there are revisions of the old one

BUT some will have to work a little on it : it was already a hellish work for me to put all that on tracing paper (and did some retouching with graphic editor) and lets say I'm not in the mood to finish all that in any CAD especially considering...

I saw some speculation that the Caline White Heat was a DOD Overdrive Preamp 250, so I found a schematic and compared it to the circuit board, but it I see no potential for it to be a DOD 250, most especially because there is only one diode on the entire circuit board. All of the schematics I've looked at to date involved at least two diodes for clipping, and another one or two in the power supply section. In this pedal it looks like the one and only diode is in power supply section. I'm hoping...
