The Hydrazine is BSRI’s take on the iconic Interfax Harmonic Percolator, but they have added a range of modern updates to give you a wider range of tones.

While staying true to the Harmonic Percolator’s sound and feel, the Hydrazine has a modified amplifier circuit to improve clarity and punch. BSRI has also included an active EQ section that provides a wide range of bass and treble frequencies to shape your tone. Finally, BSRI has added a unique “Texture” control that allows you to sweep between various clipping thresholds between transistor overdrive and fully compressed diode clipping distortion.
