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.
A noise gate reduces or mutes the signal when it falls below a threshold, separating wanted notes from hiss, hum and high-gain noise. Threshold decides when the gate closes, while attack, release and hold control how naturally it opens and how note tails decay. Side-chain or four-cable designs can detect the clean input while silencing noise later in the gain chain.
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
