JHS Pedals 3 Series Harmonic Trem

The JHS Pedals 3 Series Harmonic Trem brings the legendary “Harmonic Tremolo” effect from vintage Fender amps into a compact, affordable pedal format. Inspired by Leo Fender’s groundbreaking 1960 circuit, this pedal recreates the lush, pulsating modulation that splits your signal into high and low frequencies and alternates between them. The result is a dreamy, musical effect that sits somewhere between traditional tremolo and Uni-Vibe-style modulation. With intuitive controls and a toggle for switching between standard trem and harmonic trem, this pedal gives you vintage inspiration with modern usability.
