In the current JustPedals catalogue, Joyo is represented by Distortion Pedals, Overdrive Pedals and Amplifiers & Headphone Amps. Current listings include Cab Box, D56 Fuzz and D54 Delay. That makes the range relevant to players looking for drive, gain and clipping, plus time-based effects and ambience. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.
Tremolo varies amplitude, making volume rise and fall; vibrato varies pitch, making the note move sharp and flat. Some circuits combine both or derive them from modulation systems that blur the boundary. Rate, depth, waveform and stereo phase determine whether the motion is smooth, pulsing, choppy, seasick or spatial, while tap tempo can lock the cycle to a rhythm.
