The JHS 3 Series Harmonic Tremolo is a versatile guitar effects pedal that adds rhythmic pulsing, warmth, and movement to your tone. It combines traditional amplifier-style tremolo with a more distinctive harmonic tremolo effect inspired by vintage Fender amplifiers.

Its simple controls make it easy to create anything from gentle vintage pulses to swirling, almost phaser-like textures.

Design and appearance

The pedal features a compact, durable metal enclosure with the clean, minimalist styling of the JHS 3 Series. Three control knobs, a two-position toggle switch, and a footswitch provide direct access to its essential functions.

Its small footprint makes it easy to integrate into a pedalboard, whether you're building a vintage-inspired rig or experimenting with atmospheric modulation.
