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.

Reverb Pedals

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.

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.
