Joyo

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.

Looper Pedals

A looper records a passage and plays it back repeatedly so additional parts can be overdubbed over the cycle. Loop length, audio quality, storage and the number of independent tracks define the basic capability. Undo, quantisation, synchronisation, rhythm guides, reverse and half-speed functions determine how recordings can be corrected, transformed and aligned with other equipment.

True Bypass

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.
