Iconic Phaser Swirl in a Beautiful New Finish – The MXR 50th Anniversary Phase 90 Pedal
Released in 1972 as MXR’s first offering, 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. No matter the genre or instrument, its distinctly lush voice will elevate any musician’s tonal palette. Now, you can celebrate an illustrious legacy with a beautiful new 50th anniversary finish.
- 1 FOOTSWITCH toggles effect on/bypass (red LED indicates on)
- 2 SPEED knob controls overall effect rate
- This pedal is powered by a single 9-volt battery (remove bottom plate to install), a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or an MXR Brick Series power supply
More than a Phase
The Phase 90 has been a mainstay on the pedal boards of millions of players around the globe ever since. The greatest guitar players—from David Gilmour and Eddie Van Halen to Tom Morello and John Mayer—have used this pedal to expand the canon of rock ’n’ roll.
A Masterpiece Finish
The Phase 90’s orange finish is instantly recognizable to anyone who has ever played in a band—it is almost as much a part of its identity as the swooshes and swirls it infuses into the sound of a musician’s instrument. But MXR thinks a masterpiece pedal deserves the masterpiece treatment with this special 50th anniversary edition gold finish.
Display It or Play It
The MXR 50th Anniversary Phase 90 is worthy of a privileged place in a musician’s finest display case—but it will fit perfectly on a pedalboard, too. MXR invites musicians to celebrate its legendary legacy, whether players are admiring its luxurious sheen or basking in its spatially shimmering tones.
