MXR Phase 90 vs Boss CE-5 Chorus Ensemble
MXR Phase 90 wins for rhythmic, sweeping modulation with a distinctive character — the phaser sweeps a comb filter through the frequency spectrum, producing the characteristic warbling quality. Chorus wins for adding width and the impression of multiple guitars — it produces a more lush, thick character that is generally more subtle and widely applicable than the Phase 90's more obviously "phaser" sound.
MXR Phase 90
The iconic 4-stage FET phase shifter in an orange box. Single Speed knob controls the sweep rate — Eddie Van Halen used it on every Van Halen album. Two internal versions: Script Logo (smoother, vintage) and Block Logo (brighter, more modern).
Classic rock, hard rock — the iconic one-knob phase shifter that defined 1970s and 1980s electric guitar modulation
Boss CE-5 Chorus Ensemble
A chorus pedal splits the guitar signal, pitch-modulates the wet copy slightly, and blends it with the dry signal — creating the impression of multiple guitars playing together. The sound of 1980s clean guitar, Nirvana's Come As You Are, and classic Stratocaster clean tones.
Clean, indie, new wave, pop — thick, shimmering clean guitar tones from subtle width to obvious 80s chorus
