The BOSS EX-4 is a premium compact effects processor designed to expand your pedalboard with a huge range of creative possibilities in a streamlined format. With 120 premium BOSS effects, flexible signal routing and the ability to run up to four effects simultaneously, the EX-4 gives guitarists and bassists a powerful toolbox for building complex sounds without taking up excessive pedalboard space.

From overdrive and distortion to modulation, delay and reverb, the EX-4 provides a broad library of classic and specialised BOSS effects, alongside dedicated utility blocks such as foot volume, dual noise suppressors, send/return and divider/mixer functions. An independent global EQ provides additional control over your overall sound, while the Gear Suite feature makes it easy to configure effects using professionally tuned settings and save customised sounds for quick access.

The EX-4 combines an informative 2.4-inch colour display with intuitive controls, dedicated FX buttons and dual multi-function footswitches with colour LEDs. Manual and Memory modes provide either stompbox-style operation or preset-based control, while stereo I/O, an effects loop, TRS MIDI connectivity and external control connections allow the EX-4 to integrate with sophisticated pedalboard setups. With 128 preset memories and 128 user memories, the EX-4 provides extensive sound storage for guitar and bass.
