New Sound Possibilities

The GR-55’s powerful triple-core engine comprises two PCM synthesizers (with over 900 tones powered by the latest Roland synthesis technology) and COSM guitar modeling, featuring a virtual treasure trove of guitar, bass, amp, and synth models. Together, these combined technologies allow you to create unique, revolutionary sounds. The “Metal Synth Lead” preset, for example, combines two types of thick, brilliant synth textures with an overdriven solid-body/humbucking tone for incredible punch and power.

Lightning-Fast Tracking

Thanks to Roland’s decades of research and dedication to guitar synthesizers and powerful new pitch detection technology, the GR-55 is far and away the fastest guitar synth ever. Furthermore, the COSM guitar-modeling engine needs zero detection time, allowing the GR-55 to respond instantly and exactly as you play. The GR-55 detects pitch, velocity, and behavior for unprecedented response to your performance.

Instant Gratification

Get ready to rock … and fast! The GR-55 puts you instantly in touch with a huge library of amazing sounds, no editing required. The onboard lineup of ready-to-use presets (270, plus 297 user) takes the pain out of the process, with simple category buttons for finding the perfect sound fast. Choose from hundreds of great presets for pop, rock, and beyond, and kick-start your song or jam with unique, powerful sounds that will turn heads and raise fists.

Easy to Use

If you’re new to the world of technology, fear not. The GR-55 is powerful yet extremely friendly. For customizing sounds, the EZ Edit feature (made famous in the GT-10) and large LCD takes the guesswork out of the process. And for those who want to go deep, the GR-55 offers huge array of controllable parameters. Pros will appreciate the power of the GR-55 while beginners will love how quick and easy the unit is to operate.

USB Connectivity

The GR-55 conveniently bridges the guitarist to the desktop music production world with its two USB ports. The rear-panel port can be used one for MIDI/Audio data communication; the side-panel port is dedicated to real-time playback of audio files from a USB memory device (sold separately). The GR-55 provides foot control of USB audio playback so your hands never need to leave the guitar.
