Electro-Harmonix EHX Mod Rex Polyrhythmic Modulator Guitar Synth Effect Pedal
That listing sold. Check out the similar listings below.


The Mod Rex Polyrhythmic Generator houses four independent modulation engines—Mod, Trem, Pan, and Filter—that contain a host of effects and tweakable parameters. The Mod engine offers vibrato, flanger, chorus, and phaser, and includes a Depth and Feedback knob. The Trem modulates the amplitude of your signal. When the unit's stereo outs are used, Pan allows a wide separation of the left and right channels (but while in mono mode, it acts as another tremolo section). Finally, the Filter section gives the choice of low-, high-, and band-pass filters.

    I had the EHX super pulsar and this is way more effective and diverse with the Tremelo sounds . I also don’t need a Blurst either . On board effects are not bad and it really shines in stereo . Very effective pedal for looping and drone scapes . I wish the expression pedal was more effective ...the time based element is ok but it would really shine with the 8 step .

  • Fun.

    It takes some time to understand how everything works, and once you master the controls, you'll find this to be an extremely versatile, and fun pedal. I've used it for both Keyboards, and Guitar, and am amazing at how much you can do with it. Absolutely worth check out.
