In the current JustPedals catalogue, Joyo is represented by Distortion Pedals, Overdrive Pedals and Amplifiers & Headphone Amps. Current listings include Cab Box, D56 Fuzz and D54 Delay. That makes the range relevant to players looking for drive, gain and clipping, plus time-based effects and ambience. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.
A tuner pedal measures the input frequency and shows whether the played note is sharp, flat or in tune. Detection speed, display resolution and note range affect accuracy, especially for low tunings and extended-range instruments. Buffered or true-bypass switching changes the signal path, while mute, strobe display, reference-pitch calibration and alternate-tuning modes shape operation.
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
