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.

Graphic EQ divides the spectrum into fixed bands, parametric EQ allows frequency and bandwidth to move, and simpler designs provide broad bass, middle and treble shaping. Available boost or cut, centre frequencies, filter width and overall output level determine whether the pedal makes corrective, tonal or gain-driving changes.
