1979 '79 MXR Phase 90 Vintage Block Logo Phase Machine.

This is how we do it! Here is a 1979 '79 MXR Phase 90 in above-average "condish" for a nearly 40-year-old pedal. This pedal shimmers with lush phase-shifting tenderness. Dial it down low for long sweeps that lull you into a higher consciousness. Or dime it for an oscillating symphony of madness. This is such an amazing pedal. It's the middle-weight between little bro MXR Phase 45 and bigger sibling MXR Phase 100. This one is just right. Just ask Jimmy Page, David Gilmour and Eddie Van Halen.
