Manufacturer's Description for Boss SL-20 Slicer Audio Pattern Processor Pedal

Inject a shot of high-octane fuel into your music with the Boss SL20 Slicer. Instantly transform a guitar, bass, keyboard, or vocal into a pulsating groove instrument. 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.

Features
Instant groove and percussive-melody generator

50 Slice patterns onboard, with adjustable attack and duration, including Harmonic Slice

Tap Tempo via onboard pedal switch; internal and MIDI sync

Sound characteristics such as attack, duration, effect level, and direct level are controllable via external Expression pedal (sold separately)

Variety of output modes, including the unique 3D Panning for spacious sliced FX

Groove and Melody Maker
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 SL20 as a songwriting and recording tool. Play the sliced sounds in realtime while capturing them with Loop Record.

Flexible Control
An internal tap-tempo feature is included, as well as the ability to sync to external MIDI clock. Sound characteristics of the SL20 such as attack, duration, effect level, and direct level can be controlled by the onboard knobs or from an external Expression pedal.

Universal FX
The SL20 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(R), or any other instrument or music-playback device.

Customer Reviews
3.5 out of 5 (8 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. Written by one of our gear experts! "Fun but limited."
Sound: The sound quality on the unit itself is good. I wish it had an option to switch impedance levels - the device is obviously designed with low impedance keyboards in mind as well as high impedance guitars, but the inputs are all high impedance (and therefor the sound is a little distorted when using a low impedance source). Feature: The features on this unit are lacking. I would have to recommend purchasing the recommended expression pedal to go with it, to control attack or "duty" (release). That would make the unit much more musical, but even still you can't manipulate those options on looped tracks. There are a good number of preset arpeggio patterns, but if I was to use an arpeggiator I would want to be able to make my own. I realize this a bit much to ask of this unit, but it is still a feature I would like which this unit lacks. Ease of Use: Very easy and straightforward to use. Quality: Built like a tank, like all Boss pedals. Value: I feel that the price of the physical components is justified, but in terms of practicality it isn't worth the cost. The Wow Factor: It's a sexy unit. The black and green colors look sleek, and the tempo LED is effective and looks cool. Definitely stands out on a pedal board. Overall: Overall, it's not a bad unit. It does what is claims to do, but I found it limited musically. Maybe if I'd had a chance to use it with an expression pedal I might have been more impressed, but probably not. In the end it was fun to play with, but I'm not sure it would contribute much to my music overall.
Style of Music: Electronic, Classical

zZounds has verified that this customer bought this product from us. Written by one of our gear experts! "Less is more."
Sound: The best way to use this pedal is to not overplay on an instrument because it can create a lot of effected notes or sounds from a note or chord you are playing. The less you play on an instrument, the better it works at what it does. If you end up playing a lot on an instrument with the effect on, the sound can get muddy, unless that is what you would want to hear. Feature: The ability to adjust your tempo of the effect in three different ways; the tap tempo, the strobe light rotary knob, and a MIDI IN clock. Ease of Use: Plug in and turn the knobs to get what you would want. Let your ears be your guide. The flexibility in changing the tempo also makes this pedal really easy to use. Quality: Well made, as every BOSS pedal is. Value: Due to the fact this is a large, well made pedal from BOSS and is a bit of a novelty item, its price makes sense. Manufacturer Support: I haven't made usage of it for any BOSS products but Roland, which is the parent company, has always been helpful whenever I had questions about their gear. The Wow Factor: The best way to use this pedal is to not overplay on an instrument because it can create a lot of effected notes or sounds from a note or chord you are playing. The less you play on an instrument, the better it works at what it does. If you end up playing a lot on an instrument with the effect on, the sound can get muddy, unless that is what you would want to hear. Overall: Any guitarist should use this product if they feel like trying something different and would especially like to make a guitar sound less like a guitar and more like something electronic.
Style of Music: Rock, electro, techno, house, juke, ambient, classical, jazz, etc.
