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.

Noise Gate Pedals

A noise gate reduces or mutes the signal when it falls below a threshold, separating wanted notes from hiss, hum and high-gain noise. Threshold decides when the gate closes, while attack, release and hold control how naturally it opens and how note tails decay. Side-chain or four-cable designs can detect the clean input while silencing noise later in the gain chain.
