THE classic effects pedal for phase shifting (aka a phaser), this orange MXR Phase 90 is available for rent to Boston area musicians. It is in mint condition.
What does a phaser do? It takes the signal from your guitar and adds a series of peaks and troughs in the frequency spectrum which leads to a "sweeping" effect. When on a lower setting, the sound moves slower for broader sonic swells, while higher speeds offer more warbly motion.
Guitarists that use(d) phasers: Robin Trower, Jimi Hendrix, Brian May, Steve Hackett, Jonny Greenwood and Eddie Van Halen.
Please note: Minimum 2 night rental required.
