Boss launches compact effects powerhouse

The EX-4 Effects Expander packs 120 classic Boss pedal effects into one compact unit that frees up pedalboard space. It runs four effects simultaneously and costs $299.99.

“"An essential toolbox."”

Four simultaneous effects from vast library

The EX-4 draws from overdrive, distortion, modulation, delay, reverb, and bass-tuned effects. It also includes vintage Boss creations like the Slow Gear for violin-like swells and the Slicer for glitchy patterns.

Customizable footswitches and utility blocks

Two dual-function footswitches can be configured for presets, effect on/off, memory navigation, master bypass, or tap tempo. Utility blocks like foot volume, noise suppressors, and mixers can be placed anywhere in the effect chain.

Global EQ and colored LED feedback

A global EQ shapes the overall sound, while a colored LED system provides clear on-the-fly feedback about what the pedal is doing. This helps players see their effect settings at a glance.

Flexible connectivity for any rig

Four audio jacks support mono and stereo connectivity, with two slots for an effects loop to place external pedals in the chain. MIDI in/outputs and inputs for external footswitches and expression pedals add flexibility.

Bridge between pedalboards and modelers

The EX-4 lands between traditional pedalboards and amp modelers, offering a middle ground. It can even be hooked up to a modeler and treat it as a single external pedal within its effect chain.

“"Modern players carefully curate their pedalboard builds, and every slot must earn its place."”
