Just Tremolo – Gear Review: Joyo JF-09 Tremolo Pedal

OPTICAL PHOTOELECTRIC CIRCUIT – AUTHENTIC TUBE AMP TREMOLO: The optical photoelectric circuit recreates the warm, pulsating tremolo of classic tube amplifiers—without the need for a vintage amp.

The Rate knob sweeps from a slow, gradual pulse (1Hz) to a rapid, shimmering warble (20Hz), while the Intensity control adjusts from barely-there movement to deep, pronounced modulation. The LED indicator pulses with the rate, so you can set your tempo before you even play a note.

9 STUDIO-GRADE STEREO REVERB MODES — FROM CLASSIC TO EXPERIMENTAL: The PARA-VERB delivers a full spectrum of reverb textures with nine meticulously voiced stereo algorithms. ROOM (warm, short reflections), HALL (lush, expansive tail), CHURCH (solemn, dense reverberation), CAVE (dark, deep reflections with long pre-delay), PLATE (bright, metallic studio sheen), SPRING (vintage amp-style bounce), REVERSE (supernatural backward swells), SHIMMER (ethereal octave-up layered trails), and DREAM (slow modulation feedback with flange-like movement). HI-CUT, LOW-CUT & PRE-DELAY — PRECISE TONE SCULPTING: Unlike basic reverb pedals, the PARA-VERB features dedicated Hi-Cut and Low-Cut filters for surgical control over your reverb tail's frequency content—dial back high frequencies for a darker, vintage vibe or cut lows to keep your sound tight. The PRE-DELAY control adjusts the time gap between your dry signal and the onset of reverb, adding spaciousness and clarity. Pro tip: for subtle, traditiona… read more
