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.
Delay records the incoming signal for a chosen interval and repeats it after the original note. Feedback returns repeats to the delay line, while tone, filtering, modulation and saturation determine whether echoes remain clear, darken progressively, wobble like tape or degrade like analogue bucket-brigade circuits. Delay time and rhythmic subdivisions govern the spacing and musical pattern of the repeats.
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.
