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.

Vocal Effect Pedals

Vocal processors accept a microphone-level signal and apply effects or pitch-aware processing to the voice. Reverb and delay add space, compression controls dynamics, harmony engines generate additional parts, and formant, doubling, distortion or vocoder processing changes vocal character. Microphone gain, phantom power, feedback control, harmony tracking, footswitch access and balanced connections distinguish a stage-ready processor from an instrument-level pedal.

Reverb

Builds a dense tail of reflections around the original sound. Early reflections establish apparent distance and size, while decay, diffusion, damping and modulation shape the density, brightness and movement of the later field. Pre-delay separates the dry attack from the ambience, and mix controls their relative level.
