Boss has launched the EX-4 Effects Expander, a compact effects processor that infuses any pedalboard setup with a boost in sonic versatility. Players carefully curate their pedalboard builds, and every slot must earn its place. The EX-4 delivers up to four simultaneous effects from a vast onboard library. Every category is available among the 120 effect selections, including overdrive and distortion, modulation, delay and reverb, as well as bass-tuned effects and Boss favorites like Slow Gear and Slicer. The EX-4’s Gear Suite feature makes it quick and easy to call up ready-to-go sounds. Each effect type comes with multiple pre-made Gear Suite settings with professionally tuned parameters.
