Cool looking soft clipping overdrive using a discrete op amp setup.

Might be something for the HM-2 fans? The gyrator frequiencies and Q's looks promising...

An old polish distortion which is based on Ibanez Trash Metal. Which is basically a buffered and boosted Rat circuit with an additional fixed gyrator EQ stage after the distortion circuit.

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.
Slightly modified. Stock units had two 741 op amps but the layout is modified for a dual op amp. A 1458 will do the same job as two 741s.
Found this in an older folthe usuader that I forgot. Includes some necesarry modernazations like true bypass, onbard charge pump, input and output caps and pulldown resistors.
