From the post

There is a layout for the fuzz section in library but here comes the whole package with the inductorless wah circuit ryincluded. The wah pot can be wired as a manual panel mounted "bandpass filter" tone control or wired through an expression jack. The fuzz section is based on Foxx tone machine but there is quite a lots of changes along the signal path wiith different component values, a couple of buffer stages and negative feedback resistors. However, the Tone control match the FTM so feel free to adjust the 3,3nf cap for a higher value to bring up some mids.
