WL-9411 - "LUCY SAYS NO"


Lucy Says No is a vactrol-controlled active feedback loop - we like to call it an oscillator too. It's influenced by no-input mixing techniques and the use of feedback paths by groups such as Yellow Swans.

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.


  • 6HP wide
  • Skiff-friendly
  • 30ma draw on +12v rail, 30ma draw on -12v rail
  • 100kOhm / 1kOhm Input/Output impedence, respectively
  • Vactrol control of feedback amount


  • FEEDBACK (center knob)

    Amount of signal allowed through the feedback path, and thus the amount of feedback.

  • GAIN

    The...gain...of the feedback loop preamp.


    Output of feedback path. connect to the OUTPUT of the donor module (the module you want to have feedback)

  • SEND

    Input of feedback path. connect to the INPUT of the donor module.

  • CV

    Control voltage input for FEEDBACK control. vactrol-based, nonlinear, you know the drill. When CV is injected, the FEEDBACK knob acts as an offset.

  • OUT

    Main output of the module.


  • Types of modules that work best with LSN: filters, distortions, reverbs and delays especially! all modules will have different input impedences and circuit designs. experiment! we keep telling you to experiment please god

  • A secret: LSN's feedback loop is basically an LPG sans the "L". by patching a sound source into "RETURN", listening to the output on "SEND", and using the CV input, you can use it as a very dirty vactrol. note that due to the boost circuit the signal will always be at least slightly distorted, but this is good.
