The GR-55 is a guitar synthesizer that includes a wide variety of sounds. Not only does it feature a good selection of synthesizer sounds, the onboard COSM effect modeling gives it the ability to create some sounds similar to V-Guitar systems like the VG-88, but it isn't a full V-Guitar system. It is the follow-up to the Roland GR-33 guitar synthesizer.
Some of the factory patches are musically unusable and only exist to demonstrate the capabilities of the device. For example, the patch "Comedian" is a laughter sample transitioning into applause. That is not something likely to be useful, but it is good for a "wow, a guitar can actually do that!?" moment.
The original GR-55 shipped with 360 factory patches (270 guitar, 90 bass) and 297 user patch memories. The 1.50 firmware update expands the factory patches to 468 (360 guitar, 108 bass).
