The Phase 90 is the quintessential phaser – simple, iconic, and nails that vintage vibe. Perfect for players chasing that classic 70s swirl, especially for rock, funk, and even some subtle psychedelic textures. It's a go-to for anyone wanting a straightforward, reliable phase effect without a ton of fuss.

Product Description

MXR Phase 90, Effect Pedal

  • Effects UnitThe Vintage Phaser effect
  • just like the MXR back in the day. There is
  • of course
  • only one control with which the speed of the phasing can be adjusted
  • everything else is set in order to achieve a really pleasant
  • never too intrusive-sounding effect. The classic phasing sounds of the 70's were often created with this piece of equipment. This is how Eddie Van Halen "spiced up" his legendary Lead sound
  • especially on the early records. This can clearly be heard in his parade solo on "eruption".

, Rugged metal casing, Non-slip rubber base, Phaser with "Speed control", Power supply: 9V battery or optional power supply available

PROS
  • • Classic 70s phase tone, instantly recognizable and versatile
  • • Rugged metal enclosure withstands gigging abuse reliably
  • • Simple, intuitive single-knob control for easy speed adjustment
  • • Compact footprint minimizes pedalboard real estate impact
CONS
  • • Single control limits nuanced tone shaping capabilities
  • • True bypass is absent, potentially coloring the signal
  • • 9V battery power can be inconvenient for frequent use
