Tesla AYZ-025 Fuzz Wah

 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.

 

 

 

Tesla AYZ-033 Overdrive

 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.

 

 

 

Tesla AYZ-030 Graphic Equalizer

 An old graphic equalizer from the former Chechoslovakia. For more fidelity, LM741 could with subbed with TL071 or other low noise single op amps.

Tesla AYZ 025 (Fuzz section)

Fuzz section lifted from of a fuzz wah from former Czechoslovakia which was produced in late 70's and 80's. By looking at the schematic it shares some similarites with Foxx Tone Machine.
