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.


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

Carbon Carhartt
Size: XX-Large, Color: Carbon Heather
Classic Carhartt quality. Reasonably thick t shirt with a bit of stretch, but still sturdy and rugged. I put this on as soon as it arrived. I have nothing but a plethora of carhartt t's for the spring and summer. Added this color, Carbon Heather, to my collection. It looks plain cool. Almost like carbon fiber.

Perfect for casual or weekend wear whether working at home or relaxing
Size: XX-Large Tall, Color: Dusty Olive
Comfortable material. Durable, I ordered size 2xl tall and love that it’s a casual shirt that is long and even if I lift my arms up my belly isn’t exposed. Neckline isn’t too tight I usually prefer a v neck but this shirt is so big the neck doesn’t feel tight or constricting. Great value for its price. I will be wearing this at home and on the weekends for sure.

Classic look, great feel and great price.
Color: Black, Size: X-Large
Super comfy and casual, but classy enough that it can be worn out. I find this shirt extremely comfortable, it is a classic look and is very flattering. I wear a size 14 and the XL is loose but not baggy. It washes well, does not wrinkle if I get it out of the dryer and folded in appropriate time, and the material is a good weight for the cost of the shirt. I would likely buy again as this is a great summer staple.

Runs true to size and well made!
Color: Black, Size: Medium
I am very pleased with the size and cut of this top. I hesitated on sizing (at 5'1" and 105 lb) because I like a looser fit and am sometimes given different size recommendations. Many times the tops are too large and must be altered or simply passed on to thrift stores. This shirt in a medium is perfect in its fit, flows nicely. The neckline is not too low, but more like a shirt with a couple of top buttons unbuttoned- no gap. The sleeve length is good for me as my shoulders are a bit narrow. (I checked and no way to remove the stitches that hold the sleeve into a cuff. They are deeply embedded into this soft opaque fabric that has some stretch. (Even with the best of seam rippers and sharp eyesight!)I think the rolled cuff is cute! Top drapes well and is a great length for jeans or shorts- dressy casual wear, with its perfect fabric thickness. I really like the black color. I would not wear it with leggings because of the length, but jeggings are great with it. The little contrasting buttons are a nice touch. Great value buy.
