Ring Modulator

The Fitzgreyve 6401 is a Eurorack implementation of the Moog Bode 6401 Ring Modulator.

The core ring modulator circuit is passive, using diodes and transformers. The module includes the original Bode input buffers and Squelch (noise gate) circuit, plus a CP3 style output amplifier.

Build options:
- The full circuit
- Omit the squelch (noise gate) circuit
- As a “passive” ring modulator only
