Released in 1974, the original MXR Phase 90 was one of the company's first pedals and helped solidify the brand as a staple on pedalboards worldwide.

    The old block phase 90 is a perfect phase. It just works. Find one that hasn't been messed with internally. The new stuff is great too, but does not have that broken in feel like the old units.
