The Boss SL-2 Slicer transforms any guitar or instrument signal into dynamic, beat-synced rhythmic patterns using stereo tremolo-style slicing and motion-based effects. Building on the original SL-20, it features 88 onboard patterns across 8 types, stereo operation, tap tempo, MIDI sync, and external control options. From pulsing stutters to swirling grooves, it’s a powerful tool for adding movement and complexity to your sound, whether on guitar, synth, or any line-level instrument.
