THE LATEST MILESTONE IN GUITAR SYNTH INNOVATION

BOSS and its parent company Roland have been the worldwide leaders in guitar synthesizer innovation for nearly five decades, beginning with the revolutionary GR-500 system in 1977. The GM-800 continues our dedication to this category, providing guitar and bass players with powerful creative tools and access to sounds typically only available with keyboard-based instruments. Expanding and elevating the concepts behind many historic Roland GR products, the GM-800 merges our latest pitch and string tracking advancements with a versatile, cutting-edge sound engine.

ZEN-CORE INSIDE
The GM-800 is built around the expandable ZEN-Core Synthesis System, the sound source behind professional Roland products like the JUPITER-X and FANTOM keyboards, the ZENOLOGY software synthesizer, and many others. ZEN-Core is the most powerful synth engine in Roland’s long history, distilling decades of expertise into one sonically vast and deeply expressive creative instrument.

Over 1200 Sounds at Your Fingertips
The ZEN-Core engine combines modern PCM synthesis and advanced modeling to bring you an infinite playground for sonic discovery. Play acoustic pianos, EPs, organs, and orchestral instruments. Tap into classic Roland synths like the JUPITER-8, JUNO-106, and many others. And combine them all together to build sounds never heard before.

Four Tones Plus Rhythm
The GM-800 features four Tone parts plus a Rhythm part filled with acoustic and electronic percussion sounds. Call up a part with the dedicated panel buttons, then explore a deep array of synth parameters, pitch settings, alternate tunings, and string assignments to shape sounds to perfection.

Intuitive Scene Workflow
The ZEN-Core workflow is based around Scenes, which are “super patches” containing every element in a sound: Tone selection, parameters tweaks, sensitivity and other play settings, effects, and more. And thanks to the muscular DSP, you can carry over the sound of the current Scene as you select a new one for seamless musical transitions. There are 150 user-configurable Scenes, and 100 come with pro sounds ready to play immediately.
