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.
Looper pedals record a phrase and play it back as a repeating cycle, allowing new layers to be overdubbed, undone or replaced. Loop time, track count, memory, undo depth, fade or stop behaviour and synchronisation determine how complex a performance can become. Some loopers are simple one-button practice tools, while others add quantisation, rhythm parts, MIDI clock and multiple song sections. Check the input and output routing, footswitch layout and whether saved loops survive a power cycle before building a live workflow around one.
True bypass removes the effect circuit from the audio path when bypassed, usually by mechanical, relay or switching circuitry. This can preserve the direct signal but does not automatically solve long-cable loading, and it may create a pop or leave no buffer for the rest of the board. Check the actual switching method, trails or spillover, input and output loading and the number of other true-bypass pedals in the chain.
