Detailed Introduction

The infinite creativity of sound
The GR-55's powerful three-core engine consists of two PCM synthesizers and a COSM guitar module. The two PCM synthesizers have more than 900 tones of Roland's most advanced synthesis technology, and the COSM module contains a collection of various virtual modules for guitars, basses, amplifiers, and synthesizers.
Together, these powerful technologies allow you to create unique, completely innovative sounds. For example, the preset “Metal Synth Lead” sound is made up of two cool synth sounds, combined with an overdriven solid/humbucking electric guitar sound, giving the sound an incredibly powerful impact and force.

Lightning-fast response
Thanks to Roland's years of dedication to guitar synthesizer research and development and the extraordinary results of new pitch detection technology, the GR-55 is undoubtedly the fastest guitar synthesizer ever made.
In addition, the zero detection time of the COSM guitar modeling engine allows the GR-55 to respond immediately and accurately when you play.
The GR-55 detects pitch, velocity, and your playing movements with unprecedented speed.

Instantly meet your needs
The GR-55 does not require complicated editing procedures, allowing you to instantly access a large number of wonderful sound libraries to find the sound you like.
A comprehensive range of preset sounds (270, plus 297 user sounds) is built in, allowing you to quickly find the perfect sound without the hassle of setting up your favorite sound.
Easily choose from hundreds of sounds designed for pop, rock, and more, and instantly perform with unique, powerful sounds that will take over the audience and dominate the stage.

Easy to use
Although the GR-55 is powerful, its operation interface is extremely user-friendly. For players who want to challenge themselves to create their own sounds, the EZ Edit function (inherited from the famous GT-10) and large, easy-to-read LCD make your imagination a reality.
For musicians who want to delve deeper into fine-tuning the sound, the GR-55 also provides a large number of adjustable parameters to meet their needs.
Professionals will appreciate the powerful performance of GR-55, while novices will love its simple and easy-to-use, fast and convenient operation.
