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.
Reverb creates the dense pattern of reflections heard after sound enters a physical or imagined space. Room, hall, plate and spring models differ in reflection density, frequency decay and modulation, while ambient algorithms extend or transform the tail beyond natural acoustics. Decay, pre-delay, damping, diffusion and wet/dry balance define the apparent size, surface and distance of that space.
Converts the signal or control process into numerical data for algorithmic processing. Digital designs can provide precise timing, long memory, complex routing and repeatable presets; sample rate, conversion, internal resolution and latency influence fidelity and response.
