The Pitch Box is a Harmony Pedal with extras, featuring three different effects modes. The small, exquisite unit is protected by a full metal shell and features a true bypass footswitch, LED indicator light and 1/4" mono input and output.

Harmony shifts the pitch and mixes it back with the original signal to create a rich, harmonic voice. To output a precise polyphonic pitch shifting voice, switch the toggle to the Pitch Shift option. You can even Detune your sound by shifting the pitch just slightly, making the output have a 'spacey' quality.

The Mooer Audio Micro Series are nifty little pedals which take up hardly any space on your pedalboard, so you can play around with more effects at once
