Dubterrograph

Iron Ether makes unique effects and synth modules in Portland, Oregon. The Dubterrograph combines two beloved pedals into one enclosure: the Dubterranea suboctave synth and the Xerograph Deluxe envelope filter.

The suboctave section generates synth-like tones tracking an octave below your playing. The filter section adds envelope-controlled sweeps, wah-like textures, and deep dub bass tones. Together they create a mini synthesizer on your pedalboard.

Due to small-batch production and parts supply chain challenges, the Dubterrograph is notoriously difficult to obtain. When available, it sells out quickly. Secondary market prices run considerably higher than retail.

Relay-based true bypass, top-mounted jacks, hand-painted and machine-engraved. For bass players who want both the Dubterranea and Xerograph without taking two pedal spaces.
