JHS 3 Series Harmonic Tremolo
JHS Pedals · pedal
The JHS 3 Series Harmonic Tremolo (also called the 3 Series Harmonic Trem) is a tremolo pedal from JHS Pedals' budget-friendly 3 Series line, priced at $99. Controls include Rate (speed), Depth (intensity), and Volume, plus a Type toggle that switches between standard amplitude tremolo and harmonic tremolo. Harmonic tremolo mode splits the signal into high and low frequency bands, modulates them out of phase, then recombines them — producing a lush, swirling effect reminiscent of vintage tube-amp tremolo circuits. True bypass.

“The Type toggle is the key differentiator: in amplitude mode it produces conventional volume-dip tremolo, while in harmonic mode it splits the signal into high and low frequency components, modulates them out of phase, then recombines them …”
— from the reviews
“Depth governs intensity from subtle, barely-there shimmer through to deep, dramatic oscillation”
