Boss CE-5 Chorus Ensemble vs MXR Phase 90

Chorus wins for lush, shimmering thickness — it creates the impression of multiple guitar layers playing together by pitch-detuning the wet copy, and at moderate settings is one of the most universally flattering effects on clean guitar tone. Phaser wins for a subtler, warmer movement that enhances rather than thickens — at low Speed settings the Phase 90 adds depth and life to clean tone without the obvious detuning effect that makes chorus identifiable. For clean tone width and shimmer: chorus. For subtle warmth and movement: phaser.

Modulation

Boss CE-5 Chorus Ensemble

£99

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.

Best for

Clean, indie, new wave, pop — thick, shimmering clean guitar tones from subtle width to obvious 80s chorus

Modulation

MXR Phase 90

£89

Four-stage all-analog phaser with a single Speed knob — the swooping phase effect of Van Halen's early records. Eddie Van Halen's Phase 90 at Speed 4 is one of the most iconic pedal tones ever recorded.

Best for

Classic rock, psychedelic, blues — subtle swooping phase texture that adds movement without overwhelming the tone
