Boss GM-800 Guitar and Bass Synthesizer Pedal with Serial GK Interface, Zen-Core Sound Engine, and Onboard Sound LibraryBOSS 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.
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.
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. 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. 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.
Edit Sounds with BOSS Tone Studio
Craft Scenes in detail from your computer using the BOSS Tone Studio software for the GM-800. Set up Tones, string assignments, sensitivity, and more from a large, friendly interface. Then use the Librarian function to organize your Scenes for different songs and performances.
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.
Multifaceted Connectivity
The GM-800 features the newly developed Serial GK digital interface, which supports guitar/bass input from a BOSS GK-5 or GK-5B Divided Pickup and easy linking of multiple GM-800 units. GKC-AD and GKC-DA conversion boxes are also available for classic 13-pin GK devices, allowing you to drive the GM-800 with a Roland GK-3 or GK-3B pickup and use Serial GK devices with the BOSS SY-1000 and GP-10.
Features:
• Next-generation guitar and bass synthesizer with the newly developed Serial GK interface
• Advanced ZEN-Core sound engine derived from flagship Roland synthesizers
• Natural playing feel and solid tracking stability, realized through high-performance DSP
• Powerful Scene workflow with four Tones plus Rhythm
• Vast onboard sound library with over 1200 Tones and 70 Rhythm sounds

Great for growing minds!
I love these workbooks! We used to buy these at a local store until it closed. They help kids retain what they learned in school over the summer. The worksheet usually takes 5-10 minutes a day.
