The JOYO JF-301 is a boost pedal. It is intended for increasing signal level and driving following pedals or an amplifier harder.
Key identified features include true-bypass switching and EQ control.
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.
Boost pedals raise signal level, add gain, or do both. A clean boost leaves most of the source voice alone and pushes the next stage harder; a coloured boost changes the frequency balance as it lifts the level, while a treble or mid boost can deliberately narrow the emphasis. Gain, output, tone, presence and headroom determine whether the pedal works as an always-on preamp or a solo lift. Placement matters: before an overdrive it increases clipping, after it mainly increases level, and into a clean amp it may simply make the rig louder.
EQ changes the level of selected frequency bands rather than adding one fixed effect. Graphic, parametric and sweepable designs can remove resonances, shape a drive stage or place an instrument more clearly in a mix. Centre frequency, Q, cut and boost range, output headroom and bypass type all matter. EQ before gain changes the frequencies that clip; EQ after gain acts more like finished tone shaping, so placement should follow the problem being solved.
True bypass removes the effect circuit from the audio path when bypassed, usually by mechanical, relay or switching circuitry. This can preserve the direct signal but does not automatically solve long-cable loading, and it may create a pop or leave no buffer for the rest of the board. Check the actual switching method, trails or spillover, input and output loading and the number of other true-bypass pedals in the chain.
