JHS 3 Series Harmonic Tremolo Pedal

In 1960, Leo Fender introduced a circuit in his Bandmaster and Vibrasonic amps called the “Harmonic Tremolo” (which proved to be a misnomer, since it was a volume effect, not a pitch effect). Essentially, the amp’s signal was split into high frequency and low frequency components, with the output switching back and forth between the two, resulting in a dreamy effect similar to the Uni-Vibe.  The 3 Series Harmonic Trem allows you to utilize Leo Fender’s revolutionary effect in a package much easier to tote than a vintage amplifier.  Toggle up is a great sounding amp trem, while toggle down is our take on harmonic trem effect.

Features:

• Inspired by Leo Fender’s 1960 “Harmonic Tremolo” circuit
• Toggle Up for amp trem; Toggle Down for harmonic trem
• Volume, Rate and Depth controls
• Output switches between high-frequency and low-frequency components for a dreamy effect
