Electro-Harmonix Mod Rex Polyrhythmic Modulator Guitar Pedal with 4 Modulations

The Electro-Harmonix Mod Rex Polyrhythmic Modulator Guitar Pedal is a powerful modulation tool designed for multiple instruments to stretch your musical boundaries. The EHX Mod Rex is a kinetic tour-de-force that lets you weave compelling, shifting, musical tapestries. Whether you are a guitarist, synthesist, or electronic musician you will find it inspires your creativity and stretches your musical boundaries.
Four Modulation Powers
The heart of the pedal is its four, independent modulation sections synced in time, they are MOD, TREM, PAN, and FILTER. The MOD features great-sounding EHX Vibrato, Flanger, Chorus, or Phaser. The Depth knob lets you set the amount of the effect while Feedback controls the resonance of the Flanger and Phaser. TREM delivers tremolo, an effect that modulates the volume of your signal. The Depth control sets tremolo intensity. PAN modulates between left and right in stereo operation. In mono operation, the PAN section acts as another tremolo section, but with the wave shapes all inverted. FILTER offers a choice of a modulated LPF, HPF, or BPF. In LPF (low pass filter) frequencies above a modulated cutoff point are cut. In HPF (high pass filter) frequencies below a modulated cutoff point are cut, and in BPF (band pass filter) frequencies above and below a modulated center point are cut.
Versatile LFO Shapes
Each section also features a choice of four LFO shape options - rising sawtooth, triangle, falling sawtooth, or square wave. They affect the way the modulation transitions and provide advanced creative control over the specific section as well as the way they interact with each other.
Limitless Rhythm Options
The MOD REX delivers virtually limitless polyrhythmic possibilities. Its TEMPO component gives you nine note-length choices for each of the four modulation sections. They are independently selectable in increments starting at a whole note and ranging through subdivisions that go up to a 16th note. In addition, any of the sections can be bypassed. The MOD REXs tempo (displayed as beats per minute or BPM) is adjustable with the Tempo knob, Tap Tempo footswitch, or by using an expression pedal into its EXP input. It can also be synced to an external device with a MIDI Clock or an external pulse clock.
Seamless MIDI Sync
The pedals robust MIDI implementation enables you to sync devices quickly and easily as well as 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. The MOD REX accepts MIDI to enable it to tempo sync the modulation rate with an external device, to recall presets via MIDI Program Change messages, and to control any parameter on the MOD REX via Control Change messages.
Quick Preset Access
The MOD REX lets you save and recall up to 100 presets. It comes from the factory with 20 great programs. The pedal features full stereo input and output. An external foot controller input makes banking up and down through presets quick and easy.
Controls
The Electro-Harmonix Mod Rex Polyrhythmic Modulator Guitar Pedal features a master volume control labeled VOL, a digit display with state LEDs, and a PRESET SELECT or STORE function for recalling and storing presets. It includes a TEMPO knob to manually set the master modulation rate and a LOCK button to maintain the current tempo when recalling presets. The pedal's MOD section offers four modulation effects, alongside TREM, PAN, and FILTER sections for controlling tremolo, panning, and modulated filters. Shape LEDs display the LFO shape, while a Shape SELECT button allows changes to the LFO shape in each section. The BYPASS switch toggles between effect mode and buffered bypass, with a Status LED indicating the mode. A TAP button allows users to set the modulation tempo by tapping quarter notes, with the Rate LED displaying the current tempo speed.
