Boss SL-2 Slicer

Infuse your music with vibrant rhythmic energy and tap into an inspiring creative tool with the SL-2 Slicer. This BOSS original chops your sound into unique percussive patterns—some processed with internal filters and effects—and offers multiple output options to bring grooves to life in the stereo field.

Evolving from the legendary SL-20 Slicer, the SL-2 offers expanded capabilities in the smaller, pedalboard-friendly BOSS compact format. Elevate performances instantly with 88 onboard patterns and explore even more via the BOSS Tone Studio app. Tweak knobs to shape audio segments on the fly, and synchronize with tracks using tap tempo and MIDI. Fun and easy to use, the SL-2 brings fresh musical power to all types of creators—from guitarists and keyboardists to loop performers, DJs, and beatmakers.
