Description
Drop the Jack Rabbit into your chain and you’re not stuck with a single-flavor tremolo. Suhr built this one to cover the whole spectrum, from a slow, breathing wobble that sits behind a clean tone to a rapid, choppy pulse that borders on tremolo-as-rhythm-instrument. Rate runs from 1Hz to 20Hz, and a tempo subdivision switch lets you lock the pulse to quarter notes, eighth notes, or quarter note triplets — handy if you’re syncing to a click or a drummer rather than eyeballing a knob.
Two ways to set tempo: tap it in manually, or use strum mode to derive the rate from your picking. Five waveform shapes — Sine, Square, Triangle, Ramp, and Reverse Ramp — change the character of the pulse itself, so the same rate setting can feel smooth and vocal or hard-edged and stuttery depending on which shape you pick. Rate, Level, Depth, and Waveform controls are laid out for quick tweaks between songs, and Level adds up to +14dB of output if the effect needs to sit forward in the mix.
Built into a rugged aluminum enclosure, the Jack Rabbit is true bypass and runs on 9-18Vdc with low current draw for long battery life. An internal battery monitor checks voltage at startup and during play, flashing a warning when it’s getting low and automatically flipping to true bypass if it drops too far — no dead-battery signal loss mid-set. Reverse voltage and over-voltage protection are built in. An FX Link jack (1/8″ stereo) allows remote on/off switching and external tap control for integration with a larger pedalboard control setup.
