The M1 by Walrus Audio is a powerful multi-function modulation machine with six customized, studio-quality programs: Chorus, Phaser, Tremolo, Vibrato, Rotary, and Filter. Each program offers a wealth of options to tune, tweak, customize, and save to one of nine onboard presets. The pedal features a dedicated lo-fi knob allowing users to mix various lo-fi parameters to every program, adding subtle movement and texture or creating a massive statement with thick swirling chorus to choppy panning tremolo.
