BOSS calls the SL-2 Slicer an “Audio Pattern Processor” pedal, but the truth is that this little box simply defies categorization! The SL-2 packs the power of BOSS’ original SL-20 pedal into a much more pedalboard-friendly form factor, allowing you to chop, screw, and twist your signal into complex rhythms and percussive grooves. There are 11 distinctive rhythms at your disposal, and the tempo can be set either by the control knob or by activating the hands-free tap tempo feature. What’s more, the Type knob provides five different flavors of slice — single, dual, tremolo, harmonic, and SFX — that are a cut above traditional tremolo tones! Finally, the SL-2 is packed full of high-end features, including MIDI in, expression/control in, stereo I/O, and a dedicated BOSS app to access even more pattern possibilities.

BOSS SL-2 Slicer Pedal at a Glance:

  • Chops and slices up your signal into 11 variations of percussive groove
  • Balance and attack controls to set your mix level and the effect’s sharpness
  • Duty control to modify the length of the slice pattern’s sound
  • Tempo can be adjusted by either knob control or by accessing the built-in tap tempo function
  • Type knob switches between single, dual, tremolo, harmonic, and SFX slicer types
  • MIDI in offers greatly enhanced control possibilities
  • USB port allows for even more slice patterns via the dedicated BOSS Tone Studio for SL-2 app
  • External footswitch jack for remote control of tap tempo and other momentary functions
  • Stereo I/O for wild ping-pong slicer sounds

Five different ways to slice it

What is slice, anyway? The closest equivalent in the pedal world would be tremolo, but tremolo sounds positively quaint compared to the SL-2’s wild rhythmic gating. Still, the SL-2 Slicer covers those classic choppy tones, but its five different slice options can also transform your signal into an IDM groove or even synth-like sounds.

  • Single and Dual: These modes are relatively self explanatory. Single has one slicer; Dual has two slicers operating at the same time.
  • Tremolo: The SL-2’s tamest setting, this mode is about as close to traditional tremolo as the SL-2 can get!
  • Harmonic: This mode brings in wild modulation, adding even more complexity to your rhythmic experimentation.
  • SFX: Perhaps the most peculiar mode, SFX introduces additional effects to your signal depending on which sub-mode you choose.

Big-box features in a standard BOSS form factor

Many of Music Experience’s more experimental guitarists fondly remember the SL-20 as a modern classic, but there was one catch: it was huge. The SL-2 saws down the size by almost half without compromising functionality, and it even introduces several new features to the Slicer series! Looking for enhanced control? A MIDI in allows for timing clocks, start/continue/stop messages, and control change messages for external MIDI-compatible devices. Need to adjust your tempo or controls on the fly? Pop in an expression pedal or a remote control switch, or simply activate the SL-2’s built-in tap tempo. Last but not least, the USB input enables easy connection to the BOSS Tone Studio for SL-2 app to access a wide library of downloadable slice patterns.

BOSS guitar pedals: rugged, reliable, more than 10,000,000 sold

More than 10,000,000 BOSS guitar and bass effects pedals have been sold to players worldwide, including such top players as Yngie Malmsteen, Dave Navarro, John Petrucci, Marty Friedman, Steve Vai, and Joe Satriani.

Each BOSS pedal is housed in a stomp-ready metal box and features a rubberized stomp area and base, to help safeguard against slipping. So, whether you're a fresh-out-of-the-gate beginner, an axe-veteran designing your dream pedalboard, or anywhere in between, you can depend on BOSS's proven line of pedals to craft your tone.

What BOSS Says...

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.

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:

  • Single (1 and 2)—Rhythmic patterns that use a single Slicer effect.
  • Dual (3 and 4)—Rhythmic patterns that use two Slicer effects.
  • Tremolo (5)—Patterns with a traditional tremolo effect.
  • Harmonic (6)—Rhythmic patterns with pitch-shifting effects.
  • SFX (7 and 8)—Rhythmic patterns with different effects applied.

Shape Your Groove

With the SL-2’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 +/-12 dB 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 flows 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.
