Next-gen effects pedal with the advanced ZEN-Core sound engine and Serial GK interface.
The BOSS GM-800 effects pedal elevates guitar synthesis into a new age of natural playability and boundless creative range. Driven by the Serial GK interface, the advanced ZEN-Core sound 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 ultraversatile, the GM-800 infuses your guitar or bass with unlimited musical potential.
Over 1,200 SoundsThe 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 completely original sounds.
Massive Effects PowerThe GM-800 packs the full effects range of the 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. 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.
Next-Generation PlayabilityThe 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.
