MXR Phase 90 M101


Get ready to add some shimmer to your sound with the MXR Phase 90 - the classic phaser pedal found in the rigs of guitar's elite! From Eddie Van Halen to Dave Grohl, Josh Homme to Nancy Wilson, the Phase 90 has been embraced by discerning guitarists seeking to add a touch of magic to their solos. But it's not just for guitar - the Phase 90 works equally well on bass, keyboards, and vocals, providing smooth, watery effects to chords and muted strumming.

*Note: The Noise Floor specification refers to the pedal's ability to produce quiet, noise-free operation when no input signal is present.

The Phase 90 offers a simple single knob operation that varies the speed from subtle to fast, creating a watery warble that can be dialed in to suit any style of playing. The pedal's wide range of sounds means that it can be used for a variety of musical genres and instruments, from guitar and bass to keyboards and vocals.

The Phase 90 features an input impedance of 1 MΩ and an output impedance of 10 kΩ. Its nominal input and output levels are both -20 dBV, while its noise floor is an impressive -96 dBV. With true hardwire bypass, the Phase 90 ensures that your signal remains pure when the effect is not in use. And with a current draw of just 5 mA and a power supply of 9 volts DC, the Phase 90 is a compact and efficient pedal that can be easily incorporated into any setup.

Whether you're looking to add some psychedelic shimmer to your solos or create watery, otherworldly chord effects, the MXR Phase 90 is the go-to phaser pedal for discerning musicians. Don't settle for anything less than the classic sound of the Phase 90!
