Features

  • PT2399-based delay effect with wide range of delay times
  • Two audio inputs and outputs to allow for feedback loops
  • Time CV control with attenuator
  • High pass filter & (high pass) bypass switch

Quirks and Problems

  • Adjusting input level for second input slightly affects the level of the first input
  • High pass filter is routed the wrong way, so turning it clockwise will lower the cutoff point
  • High pass filter does not cover the whole frequency range
