Here is a schematic for an ultra simplified OC2 octaver (1 octave down, no buffered input)
Could you please transform it into a vero layout ?
I would like to add it before my 'in progress Tonebender mkII negative ground' (It would be just a switch for the octava and an internal trimmer to blend the octave down with the direct signal.
Still way too massive, even with dropped features. Check out Sabro's site for complete OC2 layout. I've built that and it's ok - just keep in mind that it is in no way simple build.
