MXR Phase 100chat_bubble_outlineFrom real comments

A deep, distinctive phaser tone beloved across genres and eras. Commenters cite iconic uses by The Clash, The Police, Marley, Billy Corgan, and Mick Jones, with bass players like Juan Alderete fans calling it their favorite phaser. Many describe it as 'whooshier' than the Phase 90, edging into flanger territory, with rich, chewy modulation. Vintage script versions are frequently singled out for superior clarity and a more subtle, refined sweep compared to modern units.

Complex circuitry drives flexible but sometimes confusing controls. Users note the pedal's ten-stage design and dense circuit board, calling it one of the most complex phaser circuits made, with over 50 resistors. The Intensity control's four labeled degree settings (45/55/90/100) are well understood, but several owners are unsure what the additional unlabeled positions do, wishing for clearer documentation or demos covering the full range.

Build quality impresses, but ergonomics and reliability draw complaints. Owners praise the hand-wired construction and craftsmanship inside vintage units, calling the board 'beautiful.' However, multiple users complain the pedal is heavy and bulky for a board, lacks any output volume control forcing readjustment of other pedals, can be noisy, and in rare cases stops phase-shifting properly, or behaves badly in parallel effects loops.
