Weave compelling, shifting, musical tapestries and slip into Modulation Madness!

With four independent modulation effects sections synced in time, the Electro-Harmonix Mod Rex offers new ways to add dimension to your sounds!

Whether you play guitar, bass, synthesizer, or another electronic instrument, the Mod Rex packs a ton of creative potential.

True stereo operation allows you to craft expansive panning effects.

Dial in polyrhythmic effects with nine different note-lenghts to choose from.

With its extensive tempo control possibilities, the Electro-Harmonix Mod Red Polyrhytmic Modulator is ready to integrate into any rig!

Seven modulations to choose from.

The Mod Rex pedal packs four individual effects sections, each with their own time settings.

The Mod section offers up classic vibrato, flanger, chorus, or phaser effects.

The Trem section provides tremolo, and the Pan section creates stereo panning effects.

The Filter section features a modulated filter with selectable lowpass, highpass, or bandpass operation.

Limitless polyrhythmic possibilities!

Each section on the Mod Rex pedal has its own LFO with four selectable waveforms.

They affect the way the modulation transitions and interact with each other.

Think modulating each section with a different waveshape is exciting? Well that's just the start!

Each section can be set to one of nine different time subdivisions (from whole notes to 16th notes).

This lets you create polyrhythmic modulation effects simply by selecting different time divisions for each section.

Extensive MIDI capabilities.

The pedal’s robust MIDI implementation enables you to sync devices quickly and easily.

You can also automate functions and changes so they occur precisely when and where you want them whether you are working at home, in a studio or live!
