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.

Pedal Power Supplies

A pedal power supply converts mains or battery power into the regulated DC outputs required by an effects board. True isolated outputs break ground paths and reduce interaction between pedals, while daisy chains share a common supply. Each output must match voltage, polarity and current demand; switchable voltages, high-current sockets, IEC or external adapters and mounting dimensions affect compatibility.
