Together with the decent phase 90, which was only equipped with a speed controller, the phase 100 is probably THE vintage phaser effect. The classic phasing sounds of the 70s are not a problem, but Eddie Van Halen liked to "spice" his legendary lead sound - especially on the early records - with an MXR phaser.
The MXR 100 can be used with a rotary switch to set different waveforms, which allows for more spectacular and modern phasing sounds. Four different intensity levels selectable via 4-way rotary switch.
This pedal is 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).
