JHS PEDALS - 3 Series - Harmonic Trem

In 1960, Leo Fender introduced a circuit in his Bandmaster and Vibrasonic amps called the “Harmonic Tremolo.”  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.
