Rory Gallagher’s MXR Phase 90

Rory mentioned using this pedal in an interview he did with a Dutch publication Music Maker in 1978. Also, it is briefly mentioned in a Guitar Player article from 1977, where it was noted that Rory liked to use the pedal “just for fooling around with” (see BRITISH ROCK GUITAR by Dan Hedges Guitar Player Books 1977)

I have a MXR phase 90 which I mess around with, on some of my records I have sometimes used the effect with accompaniment work.
