Sporting a color knob for brightening/darkening the effect, a two-way open/closed switch for employing or bypassing the pedal's clipping diodes and a low gain threshold for punch that retains tone, the Walrus Audio Messner is designed to offer one of the widest spreads of overdrive possibilities on the market. Whether you want a straight clean boost, slight bite in your signal or transparent compressed wallop, this pedal delivers all the oomph without sacrificing a guitar's character.
