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.
Delay records the incoming signal for a chosen interval and repeats it after the original note. Feedback returns repeats to the delay line, while tone, filtering, modulation and saturation determine whether echoes remain clear, darken progressively, wobble like tape or degrade like analogue bucket-brigade circuits. Delay time and rhythmic subdivisions govern the spacing and musical pattern of the repeats.
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.
