Catalinbread VariOboost

Catalinbread · pedal

The Catalinbread Varioboost Legacy Edition is a reissued version of the Portland boutique builder's very first pedal, the Varioboost, a MOSFET-based clean boost with a built-in parametric equalizer. The original Varioboost was an innovative design that combined transparent boost with a parametric one-band EQ for precise frequency sculpting, predating the boutique parametric EQ pedal market. The Legacy Edition revives this design with updated construction. Suited for studio recording, live rigs needing clean boost with EQ correction, and historically-minded Catalinbread collectors.
