Erica Synths Black Double Bass

The Double Bass from the Black Series by Erica Synths is a transistor-based suboscillator with a resonance-free low-pass filter. The circuit preferentially derives frequency divisions of -1 and -2 octaves from the square wave of an oscillator. These signals are output via separate sockets or fed into the resonance-free low-pass filter via the mix control. The original signal is always connected to the Thru socket or can be mixed with Dry/Wet in relation to the suboctaves including filter. CV inputs with their own attenuators are available for the filter and the submix.
