Suhr Koko Boost
Suhr · pedal
The Suhr Koko Boost (Black Edition) is a dual-function boost pedal combining a clean transparent boost (0dB to +20dB via the Boost knob) with a selectable midrange boost shaped by a Mid knob and a 3-position frequency switch offering three distinct midrange voicings. It uses relay-based true bypass switching and runs on 9V DC power or a 9V battery, giving players both a straightforward clean volume boost and a more surgical midrange push for cutting through a mix, in a black-finished enclosure.
