Disconnect your cabinet from the mains.
2.
Triple check the power cord polarity.

Crush Delay is an special Echo-Delay unit based on the PT2399 IC, which although able to offer 400ms of
clean delay, having a special talent for generate noisy textures. The module bases its operation on control the
PT2399 chip with circuit bending techniques, converting the unit in an advance VC digital noise generator.
This third version comes with some interesting new features like redesigned VCAs circuits, more clean range
and less depth.
