Your guitar has never sounded like this.
The GM-800 isn't just an effects pedal. It's an ultra-powerful music computer that replaces your guitar signal with the ZEN-Core engine. It's the same sound engine that powers Roland's flagship synthesizers like the FANTOM and the JUPITER-X.
Why is the GM-800 a game changer?
Une bibliothèque de sons infinie : Piano, Orgues, Violons, Synthés vintage, Basses électroniques... Le GM-800 contient plus de 1200 sons (Tones). Vous pouvez empiler jusqu'à 4 instruments + 1 piste de rythme simultanément. Vous devenez un orchestre à vous tout seul.
Le Tracking de nouvelle génération : Grâce à la nouvelle interface numérique Serial GK (utilisant un capteur GK-5), la détection de vos notes est plus rapide et stable que jamais. Le processeur comprend non seulement la hauteur de la note, mais aussi votre vélocité et votre jeu.
Moteur ZEN-Core extensible : Vous n'êtes pas limité aux sons d'usine. Le GM-800 est compatible avec Roland Cloud. Vous voulez le son d'un JUNO-106 ou d'un JUPITER-8 ? Téléchargez-les et installez-les dans votre pédalier.
Pour Guitare ET Basse : Le système supporte les deux modes. Bassistes, préparez-vous à doubler vos lignes avec des synthés Moog-style monstrueux.
⚠️ Important Note: To use the GM-800, you must install a BOSS GK-5 split pickup (or GK-5B for bass) on your instrument and use a BGK cable. If you already own a 13-pin GK-3 system, the GKC-AD converter (sold separately) is required.

FAQ – The most frequently asked questions on the web
We have compiled the top Google searches on the GM-800 to answer your questions.
1. Do I absolutely need the new GK-5 microphone?
Yes and no. The GM-800 uses the new "Serial GK" digital input.
Si vous partez de zéro : Achetez le GK-5 (guitare) ou GK-5B (basse) et un câble BGK.
Si vous avez déjà un micro GK-3 (13 broches) : Vous devez acheter le convertisseur GKC-AD pour brancher votre vieux micro dans le nouveau GM-800.
2. Does it sound "natural" or "chemical"?
That's the power of the ZEN-Core engine. Unlike older guitar synths that sounded "8-bit," the GM-800 uses high-resolution samples (PCM). A piano sound sounds like a real piano, a violin sound has the attack of a bow. It's stunning.
3. Is there any latency?
Latency has been drastically reduced thanks to the GK-5's digital connection. It's probably the fastest "Pitch-to-MIDI" system ever created. However, for percussive sounds (like the piano), a clean playing technique is recommended for optimal results.
4. Can I use my own pedals with it?
Yes. The GM-800 has stereo outputs that you can send to a PA system or sound card, but it doesn't have an effects loop for inserting your pedals into the synth's sound. It's designed to be used alongside your regular guitar sound.
5. Is it compatible with bass?
Absolutely. There's a dedicated bass mode. You'll need the GK-5B sensor (specifically designed for bass string spacing).
6. Can we play chords?
Yes, the system is fully polyphonic. You can play complex piano chords or rich string textures with your guitar.
