Octo Deco

The Octo Deco is a no-controls analog octave-up effect. No knobs, no switches. Plug in and get upper octave harmonics generated through full-wave rectification and a modernized matched Schottky diode array (replacing the germanium diodes found in vintage ringer circuits).

Designed to layer with other pedals rather than stand alone. Stack it behind a fuzz or drive for classic octave-fuzz textures, or use it on its own for shimmery, textured chords. A low-pass filter reduces noise from the rectification process. The Series 2 version features updated 8-card artwork with skull imagery.

Same mini enclosure as the rest of the October Audio single-knob range: 3.63 x 1.50 inches, 255g. Runs on 9V center-negative at 2mA, no battery option. True bypass.
