Catalinbread Pareidolia

Catalinbread · pedal

The Catalinbread Pareidolia is a tremolo-based modulation pedal that incorporates elements of phasing and pitch modulation for a character akin to a Uni-Vibe or rotary speaker effect. The combination of tremolo modulation with phase and pitch elements produces a complex, organic modulation that captures the swirling, speaker-in-motion character associated with rotating speaker cabinets and vintage Uni-Vibe pedals. Operates at both 9V and 18V for adjustable headroom. Built by Catalinbread in Portland, Oregon.
