I have yet to figure out why, but for some reason the Interfax Harmonic Percolator has become something of legend among people who are into such things. I built this thing last week and heard it in action just long enough to be satisfied that it was functioning properly.
Steve Albini, the legendary producer and storied rock n' roller, is quoted as saying that while he adores this pedal, he values his penis more. I haven't played either long enough to make up my own mind about this, but I have a feeling that mystery will remain unanswered until the end of my days. At least I can take this for a rip in my basement, which I'm excited to do. I haven't shown you any gutshots, but rest assured I used all of the mojo that was recommended in the build documentation.
This one was built on a PCB etched by me from an old pattern that Madbean doesn't sell anymore.
