MXR Phase 100
MXR · pedal
The MXR Phase 100 is a four-stage phaser with an Intensity control offering four phasing textures, a richer, more pronounced cousin of the Phase 90. Used by Glenn Tipton, it delivers lush, swirling modulation from subtle to dramatic, suited to rock rhythm and lead. Its extra control range makes it more versatile than the simpler Phase 90.
