Boss EX-4 Effects Expander Compact Multi-Effect Pedal

When it comes to classic, clean effect pedal experiences constantly meeting players where they're at, the Boss EX-4 Effects Expander Multi-Effect is a pedal to embody the full Boss ethos. This compact, pedalboard-ready multi-effect puts forth a powerful multi-effect experience with over one hundred Boss effects, a streamlined control scheme, and all the modern connectivity you need for stealing the spotlight.

The Boss EX-4 centers around a powerful multi-effect engine touting 120 onboard Boss effects. Classic Boss effects from drives to delays to modulations and even lesser-seen Boss favorites like the Slow Gear and Slicer appear across the EX-4's easily navigable interface. Four effect blocks land with the EX-4 to produce a concise, compact mix of Boss effects to call upon at a moment's notice. The pedal's two front-facing footswitches allow for quick interaction with effects. What's more, complex interactions can be mapped to easy gestures for seamless on-the-fly switching.

Over a hundred effects and quick switching isn't everything the EX-4's got loaded up, of course. Ultra-modern control opens up with this EX-4 with its onboard Gear Suite function. The EX-4 allows for programmable effect parameter presets, signal chain reordering, and 128 preset memory slots for players looking to get in the weeds with their pre-set pre-configuring. Manual and Memory playability modes allow for the EX-4 to be played in a more immediate stompbox fashion or a more pre-programmed preset fashion – whichever suits your performance style!

The EX-4 can be the center of your whole rig, it can be the only piece on your board, if that’s your cup of tea! If you're looking to work the EX-4 into an even bigger, more ambitious rig – and we know you are – the EX-4 features a number of built-in functions specifically to make it work its best alongside other pieces of gear. For one, full stereo in and out connections mean the EX-4 is readymade for your most elaborate stereo setups. For another, an onboard FX loop function allows for looping in external effects units into the EX-4's signal flow.

Further controls appear throughout the pedal to even reorder the position of FX-looped pedals in the EX-4's flow. Options for series, parallel, or even wet/dry effect routing make the EX-4 primed to perform in your most elaborate mixed-signal setups. Standard power supplies operating at at least 300mA minimum bring this whole show to life, though you can just as easily call on the EX-4's included adaptor.

A compact, streamlined way to bring the magic of Boss effects to any board, the EX-4 is one small step for Boss, one giant leap for Boss-kind.
