Zoom

ZOOM CORPORATION is a Tokyo-based Japanese maker founded in 1983. After developing audio components and rhythm equipment, it released the compact 9002 multi-effects processor in 1990 and later the popular 505 Guitar. Today its guitar, bass and acoustic processors range from small practice units to larger floorboards. JustPedals listings include the G1X FOUR and B1 FOUR, plus the A1 FOUR for acoustic instruments and its expression-pedal version. Compare each model’s instrument focus and expression controls: similarly sized Zoom units can be built around different effects and playing needs.
