Land Devices HP-2 Yellow

HP-2 is a distortion device, based on the harmonic percolator. A genuinely unusual design that is instantly recognizable. Known as a sonic doomsday device, but can easily be dialed down to add just a touch of harmonic richness. Harmonics (H) controls the input level and Balance (B) controls the output level. Rocker switches in and out the clipping section. Switch left for 1970s. Switch right for absolute destruction.

"The celebrated InterFax HP-1 Harmonic Percolator which became a major part of Shellac Guitarist Steve Albini’s signature sound had somewhat obscure origins in the early 1970’s at a Milwaukee, Wisconsin electronics repair shop run by one Ed Giese. The Harmonic Percolator makes use of rather unique circuitry utilising a combination of very obscure Germanium PNP and Silicon NPN Transistors (2N404A/1N695 + 2N3565) which pass through even order harmonics while suppressing odd order harmonics - resulting in a particularly pleasing fuzzy distortion tone. I personally consider this one of the 3 key cornerstones of a certain breed of Fuzzstortion type pedals - along with the Rat type, and Sunn Model T." - Guitar Pedal X

Note: Either control will cut the signal when fully CCW.
