The Roland GR-55 represents a revolution in the field of guitar synthesizers, according to the manufacturer: for the first time it is possible to create synthesizer sounds like piano or strings and the modeling of famous guitars and amps with only one device! The GR-55 offers triple tone generation from two PCM synthesizers (with more than 900 sounds from the latest Roland synthesizer technology) and a sound chain with COSM guitar/bass/synth/amp modeling (from the VG-99, including one-touch retuning). Thanks to years of research, the GR-55 has the absolute fastest and safest tone detection for the synth sounds, and the modeling sounds have always been completely delay-free!
