A breadboard-compatible dual non-inverter audio amp built around an opamp.
Exposes most of its internals on pins for more versatility (variable gain, simple filter, ...). Some parts are optional.
Can be stacked to create a mixer with 1 board per stereo channel and 1 board for a master volume.
A good overdrive for guitar and bass created by Beavis Audio. Schematic is based on the Electra Distortion. Transistor used is russian silicon KT312, you can find these on Ebay at very low price. If you don't have KT312, you can still use small NPN silicon like 2N2222 or 2N3904 (mind the pinout in this case), still the russian part sounds a lot better to my opinion... Maybe due to the mojo :)
