Harmonic Tremolo MkII

TREMOLO

PREAMP

The Coldcraft Harmonic Tremolo is a dual-band harmonic tremolo pedal that recreates the classic harmonic vibrato/tremolo effect heard in early 1960s Fender amps by splitting the signal into low- and high-frequency bands and modulating them out of phase. It features Speed, Intensity, Balance, Tone-cut, and Volume controls, allowing players to adjust the modulation depth, tonal balance between bands, and overall output. A built-in analog preamp boosts the signal to retain energy when the effect is engaged, and a momentary mode lets you trigger the effect only while holding the switch. It uses relay-based true bypass with selectable momentary bypass mode.
