Erica Synths Black Double Bass is unique module that combines two transistor suboscillators (-1 and -2 octaves) and lowpass filter. It does not make sound on its own, but it will turn any VCO or beeper into massive bass sound with CV control over octave mix and cutoff frequency. Sync input that resets suboscillators on incoming pulse, provides even more versatility in sound design. The module can be also provide aggressive distortion, when used with percussive sounds like bassdrums.
