And again a case of a wrong schematic......
even when a correct one exists for more than three years:

IMHO that´s unserious business not to update the files and by this help the people to make their units work properly.

So is this thing just a really high speed tremolo basically? Anyone have any clips of one?

Just transcribed this vero layout to a schematic... transistor Q3 has collector going to earth, this doesn't seem right? I've just finished building this pedal using the ggg schematic which I can confirm is WRONG.

[amsmith3]

Does your schematic match that one?

Yes, it does. My bad.

I'll alter my circuit to match this and see what happens...

[amsmith3]

Hokay, built the vero design. Works fine now. Not much modulation though. It's a nice tone that comes through, with a little bit of resonance but nothing like in the audio samples on the french page. Anyone else get similar results?

[amsmith3]

Thanks for the sample, that's pretty similar to what mine sounds like. Thanks for your help on this one guys.
