Eddie Van Halen’s MXR M101 Phase 90

This was one of the very few effect pedals that Eddie used continuously throughout his career. He first discovered it in the mid-70s, while playing together with one of his friends, Terry Kilgore, who happened to have a Phase 90 on his pedalboard (Eddie Van Halen on How He Created His Signature Sound Using MXR’s Phase 90 and Flanger Pedals).

From that point on, Eddie acquired a Phase 90 of his own and used it on many of the Van Halen songs, including Eruption, Ain’t Talkin’ ’Bout Love, and Everybody Wants Some!!. For most of the time, he had the control knob set at around 9 o’clock.

I was into Robin Trower too, but we didn’t play any of his songs, so I used it with the control set between 9 and 10 o’clock. I still use it the same way today. I just locked into that one setting, and I’ve used it ever since.

In the more recent years, Eddie developed and used his own signature phaser from MXR, named the MXR EVH Phase 90.
