Thank you for viewing. This is a vintage 1970s MXR Phase 90 effect pedal. It's a versatile phaser suitable for various genres like funk, soul, and rock, and its single-knob design makes it easy to set up. I'm selling it because I haven't used it much and have kept it stored away. Compared to the 74 reissue, the undulation is noticeably thicker, and the sound cuts through well in a band setting. The included items are all shown in the photos. To prevent any swapping, the item is sold as-is, with no returns or claims accepted.
