JHS Pedals are a phenomenon. The 3 Series expands the JHS range down into super affordable territory, but sacrificing none of their legendary build quality and tone.
This is inspired by the tremolo circuit that Leo Fender innovated in 1960, introduced in his Bandmaster and Vibrasonic guitar amplifiers. "Harmonic Tremolo" is something of a misnomer though, 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 akin to the famous Uni-Vibe.
With the JHS 3 Series Harmonic Trem, you can now attain Leo Fender's revolutionary effect in a compact package that's more affordable and, of course, much more portable than a vintage '60s amplifier! Toggle up is a great-sounding amp trem, while toggle down is JHS' take on the harmonic trem effect.
