Five decades ago, the Phase 90 launched one of the most iconic music effects companies and established itself as the pedal by which all other phasers are judged. Released in 1972 as the first offering of the upstart MXR, Phase 90 has been a mainstay on the pedal boards of millions of players around the globe ever since—including a wide range of artists from David Gilmour and Eddie Van Halen to Tom Morello and John Mayer.

No matter the genre or instrument, the Phase 90 has been there through it all to add its distinctly lush voice to the musician’s tonal palette. Join us as we celebrate that legacy with a special edition 50th anniversary finish.

The MXR 50th Anniversary Phase 90 is worthy of a privileged place in your finest display case—but it’ll fit perfectly on your pedalboard, too.
