Envelop your music in vibrant rhythmic energy with the SL-2 Slicer, an inspiring creative tool filled with colorful sonic grooves. This BOSS original chops your sound into unique percussive patterns—including many processed with internal filters and effects—and provides multiple output options that bring grooves to life across the stereo field.

Evolved from the legacy SL-20 Slicer, the SL-2 offers expanded capabilities while shrinking the size to the pedalboard-friendly BOSS compact format. Instantly elevate performances with 88 onboard patterns and tap into more via the BOSS Tone Studio app. Grab the knobs to tweak audio slices on the fly and sync to songs with 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, beatmakers, and beyond.
