The MXR Phase 100 is the bigger, bolder sibling of the legendary Phase 90 — a 6-stage analog phaser built for a wider range of sweep and a more pronounced modulation than the classic 4-stage design. First introduced in the late 1970s, it's since become a go-to for players who want lush, swirling phase tones with more depth and character.
-
4-position Intensity switch — selects between preset waveform patterns for different depths of modulation
-
Speed knob — dials modulation rate anywhere from a slow, subtle wash to fast, swirling, near-psychedelic sweeps
- 100% analog circuitry with hand-selected, matched vintage-style photoresistors for smooth, musical phase shift
- True hardwire bypass with LED status indicator
- Works great on guitar, bass, keys, and vocals
Specs: Input impedance 500kΩ, output impedance 3kΩ, max input +5dB, max output +8dB, 180° phase shift range, 6mA current draw. Runs on a 9V battery, the Dunlop ECB003 adapter, or an MXR Brick series power supply.
