http://www.roland.com/products/en/GR-S/
With the all-new V-Guitar pedals, guitarists can now enjoy the immense benefits of Roland's GK processing—the powerful technology behind the GR-55 Guitar Synthesizer and VG-99 V-Guitar System—right on their pedalboards. The GR-S V-Guitar Space features independent processing for each guitar string, giving you four amazing tones that transport your axe to a new dimension of sound, including Crystal, Rich Modulation, Slow Pad, and the multi-string emulation of Brilliant Clean.
