Hi all,
Newbie tinkerer here. I was playing around with the tycobrahe Octavia on the breadboard and decided to involve a dual op amp I had lying around.
A non inverting buffer and a non inverting gain stage with a variable gain going from 1 to 50.
No problems buffering the input and adding a clean blend after the rectification stage.
Also able to drive the rectification via the op amp without any problems that I can see.
Where I'm having problems is this: I want the op-amp driven rectification stage to drive the transistor-based fuzz stage. It oscillates, acts all crazy; there must be something glaringly obvious but I'm new and haven't figured it out yet.
A nudge in the right direction is all I ask.
Thanks
