Guitar Effects Explained - Phaser
A phaser uses a filter to sweep the frequency range of the audio input and mixes that with the original audio signal. When the signals are mixed the portions that are out of phase (or out of alignment with each other) cancel out and produce a swirling, shoowsy sound. This effect was very popular in the 1970’s and heard on countless recordings of the era in nearly every musical style.
Phasers can add some nice motion to clean strumming on ballads. A phaser can also be mix with wah when you want to get funky. When used with distortion, you get a nice Robin Trower/Jimi Hendrix/Pink Floyd mood going. Phasers are also great for single note soloing in a rock setting.

The MXR EVH Phase 90 Shifter is a limited-edition version of the legendary MXR Phase 90. The Phase 90 was instrumental in creating the guitar tones on the early Van Halen records; the swirling, spacey sound on such songs as "Eruption," "Atomic Punk," and "Ain't Talkin' 'Bout Love." The EVH 90 captures the warm, hypnotic tone of the vintage "script logo" Phase 90, and with the flip of a switch also delivers an intense, edgier phase tone. It features rock-solid internal construction and an indestructible enclosure to ensure years of flawless performance. Add to this the Van Halen-approved striped graphics from the guitar that changed the world and you have a truly unique piece of rock history.
The Electro-Harmonix Nano Small Stone Phase Shifter is everything you love about the original Small Stone in a smaller, die-cast package! It's an effects pedal that delivers full-bodied, three dimensional phasing to add a special swirl to every musical style. Blues boys and babes dig its rapidly rotating speaker effect while Country players use it to add seasoning to their chicken' pickin'. Metal-heads and Industrialists dig the Stone's jet plane woosh. No matter what your musical pleasure, the Nano Small Stone Phase Shifter is guaranteed to increase it!The rate control adjusts the speed of the phasing sweep (clockwise rotation for a faster rate). Snapping the color switch up carves into the frequency spectrum, hollowing out the sound. Fundamentals and harmonics glide in and out for an extremely pronounced shifting effect. Return the color switch to the down position and the fullness returns. In the non-color position, with the sweep speed at minimum, the effect is not as strong and if the slowest sweep is desired the color switch should be in the up position.
The MXR CSP105 Vintage '75 Phase 45 pedal reissues the rare little brother of the Phase 90 to exacting specifications. With 2 stages of phasing, the Phase 45 guitar pedal offers up its subtle and musical voice via hand-matched FETs and a hand-wired circuit board. The MXR Phase 45 phaser pedal is equipped with a bypass footswitch and a speed knob. Rotating the speed knob in a clockwise motion results in a faster phase effect, and turning it counterclockwise slows it down. The MXR phaser pedal is powered by a single 9V battery, accessed by removing the stompbox's bottom plate. Texture your tone without overpowering your sound with the limited-edition Vintage '75 Phase 45 phaser pedal.
