SAF

Limited-edition "Songs About Fuzzing" Harmonic Percolator built and biased to classic percolator specifications. Features a hand-selected NOS 2N404A PNP germanium transistor paired with an NPN silicon transistor, the original transistor combination used in the Interfax circuit.

The germanium transistor pairing gives the SAF a warmer, more vintage character compared to the all-silicon HP-X variants. A three-position clipping switch selects between germanium diodes, diode lift for all-transistor distortion, and silicon diodes.

Captures the authentic even-order harmonic saturation of the original Harmonic Percolator with NOS components. Handmade near Philadelphia, PA.
