Reverse Avalanche Synth

Nano, Micro and Mini drone synths versions with extra passive LP filter based on the Super Simple Oscillator as described by LMNC.

This circuit uses S9018 NPN transistors wired backward in reverse avalanche mode so it can run on 9v (which somehow limits its range). The transistor’s collector and emitter are wired the “wrong way” across a RC circuit with a floating or clipped base and has a raw, primitive sound.
