From the post
The Velvet Fuzz is a unique fuzz that combines amp emulation and 2 different selectable fuzz tones. The toggle selects between a LM386 (Tight) circuit, and a 2N5089 (Big) circuit. These then push a Plexi Drive circuit that gives the Marshall amp emulation. The modular nature of this design gives you the option to have not only a Velvet Fuzz, but a Plexi Drive in the same box. The board is laid out for board mounted pots and I've included trimmers to help bias the J201 JFETs. I've also included a switch diagram to show how to wire the toggle switches.
