Dunlop MXR M107 Phase 100

This big brother of the Phase 90 offers a broader range of sounds in a larger unit. Along with the speed control there is a four-position rotary switch that selects four different intensities, defined as preset waveform patterns. Between the intensity and speed settings, you'll find quite a supply of excellent sounds tucked away in this orange casing. This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included). Controls: Footswitch toggles effect on/bypass (red LED indicates on) Intensity knob selects one of four preset phase waveforms Speed knob varies rate of phase sweep
