MXR has combined two of the most-used phaser pedals ever made in the MXR Mini Phase 95 pedal. The original Phase 90 pedal was a four-stage phaser that practically defined the phaser sound for electric guitar, and the Phase 45 that followed was a two-stage phaser that delivered a smoother sound that blended better with certain music styles. You get both flavors in the MXR Mini Phase 95 pedal, switchable with the 45/90 toggle switch. The "Script" switch toggles feedback in the effect, providing a pronounced sweep when on and a lusher, more subdued sound when off.
