Boss GM-800 Gitarreffekter

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.
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.
The streamlined GM-800 flows smoothly from desktop operation to installation on an advanced pedalboard. The four footswitches default to Scene selection and two unique control settings, such as pedal hold, pitch bend, or Tone selection. But you can freely assign them to control a variety of functions via a powerful Assign matrix. Two external control jacks are also available, each supporting up to two footswitches or an expression pedal. And with five-pin MIDI I/O, you can interface with MIDI equipment from vintage to modern.
