A reissue of the much beloved Phase 100 and similar in build to the renowned Phase 90, the MXR M107 Phase 100 Reissue gives you more phasing choices than ever before. Taking its cue from the original '70s model, you get smooth, gorgeous phasing and the chance to choose between four selectable waveforms. Dial up the speed for some crazy phasing or dial it back for a more relaxed vibe; either way, you get the killer sound inherent in an MXR phaser.
