Stereo Vactrol-controlled Active Feedback Loop
Stereo version of our Lucy Says No feedback module - this version is essentially two separate LSN circuits with added gain control for each channel, and a mode switch for linked (LEFT channel FEED and GAIN knobs control both channels, for stereo use) and solo (LEFT controls LEFT, RIGHT controls RIGHT, for dual mono use).
Functioning similarly to feedback loop devices found in the effects pedal world, LSN differentiates itself by being voltage-controlled. CV given to LSN controls a vactrol placed in the middle of the feedback loop, letting more or less signal through. LSN works best with delays, filters, and other modules that process and incoming signal, but as always experimentation is encouraged.
