The Roland GR-55 is a revolution in guitar synthesis, with features never before available in any guitar processor. In terms of speed, it's the fastest ever. It's also the most accurate, thanks to newly developed pitch-detection technology. As for sound, the triple-core generator houses a world-class array of virtual guitars, basses, amps, and synth voices, enabling tones and textures that have never been heard before. Onstage or in the studio, you can instantly access the GR-55's huge library of ready-to-use sounds, from pop to rock and beyond, with quick-access category buttons. Welcome to a groundbreaking new era in guitar synthesis!

What makes the GR-55 so unique and powerful is that its the only Roland guitar processor to combine COSM-based V-Guitar modeling technology with a PCM synthesis engine. This gives you the best of everything in one: instrument and amp modeling, instant alternate tunings, multi-effects, and sample-based synthesis (thats right—piano, drums, and much more).

With the GR-55s instrument modeling, you can change the sound and tuning of your guitar or bass at will. A variety of electric and acoustic stringed instruments are available, plus synth-type modeled sounds like the GR-300, Wave Synth, Filter Bass, Crystal, and others. Theres also a huge selection of COSM amps and cabs for dialing in your tone, plus lots of great effects.

The PCM side of the GR-55 contains two sample-based synth engines, each loaded with sounds from Rolands legendary keyboard synth library. The synth engines can be layered together and combined with the straight and modeled tones any way you like. PCM gives you access to the real instrument sounds I talked about before—acoustic and electric pianos, organs, strings, brass, drums, sound effects, and many more.
