DOOM 2 is an original fuzz circuit that turns your input signal into something resembling a sawtooth wave. Unlike most fuzz-style circuits, DOOM 2 responds to your playing technique and retains note dynamics . This opens up a range of uses beyond that of a conventional fuzz. Low gain settings produce the harmonic texture of a vintage synthesizer. The power and presence of a key bass is now available in the analog domain.

No circuit changes for 2024. HIGH GAIN MOD available on request.

Doom 2 (blood red)

DOOM 2 is an original fuzz circuit that turns your input signal into something resembling the sawtooth wave of a vintage synthesizer. Unlike most fuzz-style circuits, DOOM 2 responds to your playing technique and retains note dynamics.
New for version 2 is the you’re / your switch. You’re is the classic DOOM sound - strong upper harmonics, a mid-focused sound, and octavia / ring modulator effects as you play up the neck. Your is a new mode that has a stronger fundamental, more low end and fewer harmonics. This mode sounds more like a traditional fuzz.

Doom 2 Gray (mat white fluorescent)

The Chromatron is the result of 10 years tweaking, refining and reimagining the state variable filter circuit. It is an
optically-controlled analog filter that can switch between envelope control and manual control via expression pedal
with the push of a button. The envelope detector is an original design, producing a musical filter response that spans a
broad range of tones from vintage quack to future-synth psychedelica.
