The BOSS SL-20 Slicer instantly transforms a guitar, bass, keyboard, or vocal into a pulsating groove instrument and will inject a shot of high-octane fuel into your music. You can choose from 50 onboard Slice patterns or experiment with the SL20's innovative Harmonic Slicer feature, which generates percussive melodies, Loop Record, and unique 3D Panning.
The SL20 transforms your music into percussive "chopped" grooves. Fifty rhythmic patterns are onboard, with adjustable note attack and duration, plus amazing Harmonic Slice effects. Create high-energy patterns onstage in real-time, or use the SL-20 as a songwriting and recording tool. Play the sliced sounds in realtime while capturing them with Loop Record.
An internal tap-tempo feature is included, as well as the ability to sync to external MIDI clock. Sound characteristics of the SL-20 such as attack, duration, effect level, and direct level can be controlled by the onboard knobs or from an external Expression pedal.
The BOSS SL-20 is an addictive effect that inspires creativity. It's great for guitarists, but it's equally useful for other instrumentalists as well. Plug in a bass, keyboard, iPod®, or any other instrument or music-playback device. DJ's and dance-music artists will also love the SL20 as a rhythmic-performance tool.
