JOYO Technology is a Shenzhen music-gear company whose range goes well beyond stompboxes. Its official catalogue covers guitar and bass amplifiers, acoustic and busking amps, effects, power supplies, interfaces, wireless systems and accessories. JOYO also says it develops acoustic-core technology and has applied for utility patents. JustPedals listings include the JF-21 Splinter distortion and JF-319 Green Legend overdrive, alongside mini amps and power adapters. That breadth matters when comparing products under the JOYO name: some are effects, while others support the rest of a guitar or bass rig.

Chorus mixes the dry signal with one or more short, continuously modulated delays. The small pitch and timing movement between the paths creates width, shimmer and the impression of several instruments playing together. Rate controls the modulation speed, depth controls its excursion, and delay or mix settings determine whether the result is subtle thickening, a liquid wobble or a broad stereo image.

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.
Clips the waveform firmly and adds a dense series of harmonics with compression and sustain. The clipping devices, gain stages and tone filters determine whether the result is tight, smooth, mid-focused, scooped, grainy or deliberately abrasive.
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.
