From the vendor
A brutal, complex 18V distortion from ToneCzar, reverse engineered at freestompboxes.org (credited to abfackeln). Four OPA2604 op-amps, LND150 depletion MOSFETs, a 2N5457 JFET and a pair of 2N1306 germanium transistors, with a three-band EQ, gain-mode, phase and mid-voicing switches and an expression pedal input. The post links the schematic and parts list and a PCB, and shows a verified vero layout.
