JHS 3 Series Rotary Chorus

The JHS 3 Series Rotary Chorus - Classic Spinning Speaker Effect in a Compact Pedal

Authentic Rotary Chorus for Vintage and Modern Tones

The JHS 3 Series Rotary Chorus brings the classic rotary speaker effect into an affordable, easy-to-use stompbox. Originally designed for Hammond organs, the rotary effect became a staple in iconic guitar tones, heard on tracks by The Beatles, Stevie Ray Vaughan, John Mayer, and Soundgarden. This pedal captures that legendary swirling modulation, offering everything from subtle chorusing to rich, immersive rotary speaker simulation.

Simple Controls for Maximum Versatility

Designed for both beginners and professionals, the 3 Series Rotary Chorus features a streamlined control layout with three knobs and a toggle switch. The Volume knob adjusts the overall output level, ensuring seamless integration into any setup. Intensity controls the depth of modulation, allowing you to shape the effect from a subtle shimmer to a deep, immersive swirl. The Speed knob adjusts the rate of the rotary effect, mimicking the classic slow-to-fast ramp-up of a vintage Leslie speaker.

Room Toggle for Added Depth and Ambiance

A unique Room toggle switch enhances the pedal’s versatility by adding a natural, roomy reverb ambiance to the effect. When engaged (up position), this setting emulates the atmospheric reflections captured by a room mic on a real rotary speaker, giving your tone a spacious, three-dimensional quality. Switch it off (down position) for a more direct and focused rotary sound.

Compact, Pedalboard-Friendly Design

Like all JHS 3 Series pedals, the Rotary Chorus is built with high-quality components in a durable, minimalist enclosure. It features a standard 1/4” input and output for easy connectivity, and the simple interface makes it easy to dial in the perfect sound for any musical style. Whether you need subtle modulation for clean chords or an intense rotary swirl for psychedelic solos, this pedal delivers vintage-inspired tones with modern reliability.

Built for Gigging and Studio Use

With its compact size and user-friendly design, the JHS 3 Series Rotary Chorus is perfect for players looking to add a classic rotary effect to their rig without the complexity or cost of traditional rotary speaker units. Whether you're chasing the legendary tones of the past or exploring new sonic landscapes, this pedal offers inspiring modulation in an intuitive package.
