JHS Pedals 3 Series Ring Modulator Effects Pedal

The JHS Pedals 3 Series Ring Modulator is a compact, affordable way to explore everything from gentle wobble and tremolo-like movement through to clanging, metallic sci-fi tones. With two distinct ring mod flavours in one box, simple controls and a wide usable range, it is equally at home adding subtle animation to chords or completely tearing your signal apart for experimental soundscapes.

At its heart is a variable-frequency ring mod circuit with a Blend control, so you can dial in as much or as little of the effect as you like. A three-knob layout keeps things intuitive, while the Mode toggle unlocks two very different personalities: Earworm mode for moving, LFO-driven modulation, and Green Ringer mode for octave-rich textures. Whether you are into ambient, synthy sound design or want a unique twist for riffs and leads, this pedal puts a huge palette of sounds at your feet.

Because it is modulation-based rather than a gain or drive circuit, the 3 Series Ring Modulator plays nicely with your existing pedals. Use it after drives for harmonically complex lead tones, before delays and reverbs for evolving pads, or as a wild card on a synth or drum machine. From studio experimentation to live performance, it offers a powerful way to step outside standard chorus, phaser and tremolo territory.

Earworm Mode: Moving, LFO-Driven Textures

Flip the Mode toggle down into Earworm mode and the 3 Series Ring Modulator adds an auxiliary LFO that modulates the ring oscillator. This creates pulsing, shifting movement that can be as gentle or as disorientating as you like. At low Frequency settings you get hypnotic, tremolo-like swells, while higher settings introduce swirling, robotic overtones that evolve under your fingers.

Green Ringer Mode: Octave-Enhanced Ring Mod

With the Mode toggle up, the pedal becomes a Green Ringer style octave-enhanced ring modulator. Here the Tweak control blends in octave content, adding upper-harmonic bite and clang to your core tone. This mode is ideal for cutting, bell-like leads, glitchy single-note lines and harmonically rich textures that slice through a mix without needing extra gain.

Simple Controls, Huge Range

The three-knob layout keeps operation straightforward while still offering a wide sonic range. Blend sets the mix of dry and effected signal so you can keep your fundamental tone intact or go fully into alien territory. Frequency adjusts the oscillator speed, taking you from slow, throbbing movement to high, metallic chime. Tweak changes function depending on the mode, either shaping the modulation behaviour or controlling octave blend, making it easy to fine-tune the effect for any part.

From Subtle Movement to Extreme Sound Design

This is a true range pedal, capable of everything from barely-there motion to full-on dissonant chaos. Keep the Blend low and Frequency modest for a touch of animation that feels almost like a quirky tremolo. Push the Frequency higher and increase the wet mix for classic ring mod clang and sci-fi bleeps. Between the two modes and interactive controls, you can cover experimental rock, ambient, electronic, soundtrack work and beyond in a single, pedalboard-friendly unit.

• Two Flavours of Ring Mod in One Pedal - The Mode toggle switches between Earworm mode and Green Ringer mode, giving you both LFO-modulated ring modulation and octave-enhanced textures in a single compact unit. This saves space on your board while massively expanding your tonal options.
• Blend Control for Usable, Musical Tones - The Blend knob lets you mix your dry and effected signals, from a subtle layer of movement to fully wet, metallic dissonance. This makes it easy to integrate ring modulation into real-world songs without losing your core sound.
• Wide Frequency Range from Pulse to Chime - The Frequency control sweeps from slow, pulsing modulation to fast, bell-like tones rich in harmonics. Low settings can mimic tremolo-style movement, while higher settings deliver classic ring mod clang and futuristic textures.
• Mode-Dependent Tweak Control - Tweak changes role depending on the selected mode, acting as a modulation-shaping control in Earworm mode and an octave blend in Green Ringer mode. This dual functionality gives you precise control over movement and harmonic content without complicating the interface.
