The BOSS SL-2 Slicer effects pedal 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 classic SL-20 Slicer, the SL-2 offers expanded capabilities while shrinking the size to a pedalboard-friendly, compact format. Take your tone to new levels with 88 onboard patterns, and tap into hundreds more via the BOSS Tone Studio app. Use 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 Slicer brings fresh musical power to all types of creators, from guitarists and keyboardists to loop performers, DJs, beatmakers and beyond.

Shape Your Groove

With the SL-2 Slicer’s efficient interface, you can dial in sophisticated textures in seconds. Use the Attack control to shape the edge of the waveform for everything from hard-chopped slices to soft, fluttering movements. Then, tweak the waveform’s length with the Duty control, going from sharp, percussive transients to longer, fuller audio blocks. Adjust the tempo with the dedicated knob, or hold the pedal switch to engage tap tempo mode for hands-free control. And with the Balance knob and +/-12dB of output level adjustment, you always have complete control of the mix.

Set the Stage

The SL-2 dishes up loads of impressive sounds with a standard mono setup. But things get even better when using the two outputs and seven different output modes. Send direct and effect sounds to different destinations for recording and performance. Or, surround yourself and listeners in animated movement using a variety of stereo and 3D processing options. You can also feed the SL-2 with your favorite stereo pedals to bring further magic to your grooves.

Stereo output modes
Fixed (default): Sends the same direct/effect mix to both outputs
EFX/Direct: Sends the effect sound to Output A and the direct sound to Output B
Random: A stereo effect that randomly outputs the Slicer sound to the left, right or center
Ping-Pong: A stereo effect that alternately sends the Slicer sound to Output A or Output B
Auto: A stereo effect that smoothly pans the Slicer sound between Output A and Output B
3D Cross: Advanced spatial processing moves the Slicer sound in left/right and forward/back patterns in 3D space
3D Rotation: Advanced spatial processing rotates the Slicer sound in 3D space

Expand Your Creative Flow

With its generous external control options, the SL-2 works with your creative needs. Plug in an external footswitch to instantly tap in the tempo, or engage the effect with momentary presses. Or, connect an expression pedal to control knob parameters or the overall level as you perform. With the TRS MIDI input, you can sync your SL-2 grooves to a drum machine, DAW or any other device that sends MIDI clock. It’s also possible to control expression, tempo and bypass functions via MIDI CC messages.

Compact Audio Adrenaline

The SL-2 brings massive sonic groove muscle to the compact pedal format. Modern DSP takes the BOSS Slicer engine further than ever before, delivering rich, animated sounds via single and dual paths chained with multiple internal effects. Eight pattern types—each with 11 variations—will keep you armed with creative firepower for a long time. When you’re ready for more, connect to BOSS Tone Studio over USB to audition and load alternate patterns into the pedal and organize memory setups for different songs.

Pre-loaded pattern types
