MXR M107 Phase 100 Phaser Pedal

With both a Speed control and a 4-waveform Intensity control, the Phase 100 offers a broad range of sounds 

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).

This big brother of the Phase 90 offers an even broader range of sounds. Along with the speed control there is a 4-position rotary switch that selects between four different intensities, defined as preset waveform patterns. Great for guitar, bass, keys, vocals, and more!
