The Electro Harmonix Ring Thing Ring Modulator presents state-of-the-art modulation control allowing the user to explore a new sonic world that is both familiar and inventive. Complex modulations with interactive parameters create any sound your mind can imagine. Articulate pitch shifting, preset tuning, selectable waveforms, and external control deliver sound designer mystery with a Rock and Roll edge.

Blend Knob and Wave Knob

It is a wet-dry control for the effect outputs, and the wave kob changes the waveshape of the modulation signal working in two different ways depending on the selected mode.

Filter Rate Knob

It acts as a low pass filter in all three-ring modulator modes and as a modulation RATE control pitch shift mode.

Fine/Depth Knob

It controls the ring modulator frequency and pitch shift amount but with a more limited range than the COARSE knob.

Coarse Knob

It controls the ring modulator frequency and the pitch shift amount in their respective modes.

Mono/L and R Output Jacks

When in a mono output configuration, use the MONO/L output. When using a stereo output configuration, use both the MONO/L and R output jacks.

Exp Input Jack

This ring thing allows for expression pedal input via the EXP input jack.

MOD Input Jack

It connects a modulation source and sets the WAVE knob to full counter-clockwise to enable external modulation. It features an INST Input Jack, which is the main input jack.

Bypass Footswitch/Status LED

It toggles the ring thing between effect mode and bypass mode.

Preset/Tune Footswitch

It performs two functions, first, loading and cycling through presets and second, tuning the ring modulator to the incoming signal at the INST input jack.
