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.
Wah and filter pedals move or emphasise a frequency range to create a vocal sweep, resonant peak, cocked-wah tone or envelope-controlled response. A treadle wah is controlled by foot position; an auto-filter follows playing dynamics or a control source. Sweep range, resonance, Q, bias, input loading and bypass all change the feel. Check whether the circuit prefers to see the guitar directly, how it handles bass or synth signals and where it should sit around fuzz, overdrive and modulation.
Bass products are designed or voiced to retain low-frequency information and usable headroom with bass guitar or other low-register sources. Controls may centre on clean blend, low-end EQ, compression, crossover points or drive character. A guitar pedal can sometimes work well on bass, but it may remove the fundamental or compress the transient. Check the frequency response, input impedance, output level and dry-signal path with the intended tuning and amplifier.
