Brand
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.

Specialist effects alter the signal in ways that do not sit cleanly inside one established family. They may use granular processing, frequency shifting, resonators, freeze or sustain, bit reduction, ring modulation, feedback networks or combinations of several techniques. The relevant distinction is the underlying process, its tracking or latency, and how completely the dry signal can be blended or replaced.

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.
