Blends in moving harmonies and chords for a distinctive alternative sound.

Electro-Harmonix's Frequency Analyzer XO is a guitar effect pedal that adds moving harmonies to the note or chords being played. Unlike other ring modulators, the Frequency Analyzer has controllable high-order filters that reduce cross-distortions and enhance the variations. The Fine control lets you set a single frequency that will then be both added and subtracted from the original note or chord. The pedal's blend control lets you mix the new notes with the original. This is a must-have esoteric pedal, especially for techno cats.

Electro-Harmonix Frequency Analyzer XO Guitar Effects Pedal Features:

  • Analog ring modulator
    Blend, Fine, and Shift controls
    True bypass
    Tough and compact die-cast chassis
    40DC-100 power supply included

  • John McLaughlin sound

    As reviewed by Wakajawako on 4/20/2011

    McLaughlin uses this effect (or something veerrrrrry similar) on the MO Emerald Beyond album. It makes your lead lines very dissonant, creating an avant garde string of notes. Not really recommended for chords. Though when put on it's lower settings it acts as a Quasi-octave divider. Used sparingly (one song per gig), you will make all the musicians in the audience stop in their tracks to try and figure out what you're playing. I've had a number of guitarists inspect my pedalboard asking questions about the funky sounds I conjure up. My only negative on this effect is that it is underpowered. You can be rockin out a solo, and as soon as you hit this pedal your volume drops off. There is no gain control on it. So be sure to compensate by turning up your axe, amp, or boost.
