Interstellar Burst Envelope Filter

The Interstellar Burst is an envelope filter or auto wah based on the green DOD 440.  I built one for some friends doing a complete performance of OK Computer and had to make it a regular offering.  Reversed engineered from my original with a custom hand rolled opto isolator it's full of awesome Radiohead type tones.  Level controls the sensitivity of the filter and the range sweeps the frequency from peaky treble to wooly bass.  True bypass with polarity protection, like all my pedals runs off 9v adapter only (boss style center negative 2.1mm).  Current draw ~1mA.  ​$150CAD shipped.

Temporarily discontinued.
