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-D V-Guitar Distortion offers unique distortion and synth tones produced by independently processing each guitar string, giving the modern player an array of fresh, bold sounds for their sonic arsenal.
