GM-800 Guitar Synthesizer
BOSS Guitar Synthesis Evolves with the Power of ZEN-Core
The GM-800 elevates guitar synthesis into a new age of natural playability and boundless creative range. Driven by the newly developed Serial GK interface, the advanced ZEN-Core engine unlocks any sound imaginable—from acoustic instruments to classic and modern synths—while high-performance DSP delivers tracking stability and expressive scope never before possible. Freely combine and edit Tones with the intuitive Scene workflow, color sounds with a huge selection of effects, and explore a universe of fresh content on Roland Cloud. Compact, streamlined, and ultra-versatile, the GM-800 infuses your guitar or bass with unlimited musical potential.
NEW TRACKING SYSTEM
NEXT-GENERATION PLAYABILITY
The GM-800 delivers accuracy, stability, and real-time playability standards that far exceed previous systems, realized through skilled BOSS engineering and a high-speed processor dedicated solely to tracking. Multiple velocity and feel parameters let you dial in the optimal response for every sound and style. For example, you can set a Scene with piano sounds to respond to every dynamic nuance—from soft to loud—while setting another Scene with vintage analog synth sounds to the fixed velocity response found in the original instruments.

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.
Roland Cloud Expansion
The GM-800 supports an ever-growing range of creative options through Roland Cloud. Stay inspired with ZEN-Core Sound Packs and Wave Expansions. And play the ZENOLOGY synthesizer and legendary Roland instruments in your DAW from your guitar or bass. You can start using Roland Cloud right away with a free Roland Account and access additional content via three paid membership levels. All plans start with a free 30-day Ultimate trial to experience everything Roland Cloud has to offer.
MASSIVE EFFECTS POWER
The GM-800 packs the full effects range of the modern ZEN-Core system. With an immense variety of effect types available in each Scene, you can shape, enhance, and mangle sounds to your heart’s delight.
Dedicated MFX for Each Part
Along with their sound-shaping parameters, every Tone and Rhythm part has a dedicated MFX processor. Each offers over 90 effect types, including distortions, filters, mod effects, delays, and more. Many selections include two effect types for additional sound-shaping control.
Scene and System Effects
Within every Scene, you also get two additional FX for processing the combined sound, plus high-quality chorus/delay and reverb effects with independent send levels from each part. And with the Master Comp and EQ, you can shape the GM-800’s sound output for any recording or performance setup.
Audio/MIDI Interface
With a single USB cable, you can capture GM-800 sounds as audio tracks in a DAW and “re-synth” sounds in a similar way to the re-amp technique used with standard guitar tones. A Guitar to MIDI function is also available, allowing you to play virtual instruments over USB and trigger hardware sound modules via the MIDI output.
