The Gilmour Phaser
The Pedal which started it all for MXR was the famous Phase 90 (1974) waaaaaay before Jim Dunlop bought the company out (1987).
The Phase 90 was obnoxious, sweet, Harsh and delicate all at the same time. Later use by EVH later in the decade made it one of the most famous pedals of all time however back in ’74 a model called the Phase 45 which was somewhat more subtle meant everyone could have a phaser which suited them.
We urge you to compare this with the other vintage phasers on TonePedia as they all have their own specific flavours, many people find they prefer something different than the one the first expected to like!
