I built the
Madbean Snarkdoodle PCB to Tube Sound Fuzz Specs using big axial caps and it sounds killer.
You have the derivative of it on your site, the Way Huge Red Llama, but this one doesn't have the boost switch. And all veros of both of these that can be found online don't use axial caps. So how about your version of it?
Here are
some online schematics.
Thanks!
