INTRODUCTION

The Particle Germanium Fuzz is an adaptation of the Interfax HP-1 Harmonic Percolator, an extremely

rare and highly sought-after fuzz/overdrive from the mid-1970s. Not much is known about the history of

the unit other than that they were made in Milwaukee, Wisconsin by Ed Geise, owner of an electronics

repair shop called Interfax Electronics.

The Harmonic Percolator is a two-transistor fuzz, but it bears no resemblance to any other of its

contemporary pedals such as the Fuzz Face or any of the Tone Bender variants. It uses a PNP germanium

transistor paired with an NPN silicon, allowing it to run in a standard negative-ground configuration.

The transistors and some of the components were gooped or obscured in the original. To add the

mystery, there were several circuit changes made throughout the run, so even if you manage to find one,

there's no guarantee that it's one of the "good" ones.

The Particle is an exact replica of the known schematics of the Harmonic Percolator, but with one

addition. The Harmonic Percolator uses clipping diodes (unlike most germanium fuzzes) and so as with

other Aion FX projects, we've added a diode switch to go between two different sets of diodes, or to

disengage the diodes entirely.

The Harmonic Percolator was also the basis for the Catalinbread Karma Suture, which is available in

both germanium and all-silicon versions. The Karma Suture was

Fuzz.

USAGE

The Particle has the following controls:

• Harmonics controls the signal level coming into the transistor fuzz stage. Its effect is nearly

identical to rolling back the guitar volume.

• Balance is an output volume control.

• Diodes selects between three sets of clipping diodes.
