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.

Does your schematic match that one?


Yes, it does. My bad. :slap:

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

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?

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