It provides more than 1,200 preset tones, over 70 drum kits, four playable Tone parts plus Rhythm, extensive effects, and advanced pitch tracking in a compact floor-based performance processor.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for guitarists and bassists using a compatible divided pickup, the GM-800 supports layering, alternate tunings, individual-string assignments, fret-range assignments, and continuous or chromatic pitch behavior. Its 150 Scene locations store complete performance setups, while four onboard footswitches and two external control connections provide hands-free access to sound changes and assignable functions onstage.\u003c\/p\u003e\n\n\u003cp\u003eThe GM-800 also functions as a USB audio\/MIDI interface and standalone ZEN-Core MIDI sound module. Serial GK input and output support compatible GK-5 and GK-5B pickups and expansion between Serial GK devices, while standard five-pin MIDI, USB computer connectivity, USB flash-drive storage, stereo outputs, and BOSS Tone Studio integration support live, studio, and computer-based workflows.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eZEN-Core Synthesis Engine:\u003c\/strong\u003e Provides more than 1,200 preset tones spanning acoustic instruments, keyboards, orchestral sounds, classic synthesizers, and modern electronic textures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerial GK Tracking:\u003c\/strong\u003e Uses BOSS's digital divided-pickup interface with dedicated high-speed processing for accurate guitar and bass tracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Part Sound Structure:\u003c\/strong\u003e Combines four playable Tone parts with a dedicated Rhythm part for layered and split performance setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150 Scene Locations:\u003c\/strong\u003e Stores complete performance configurations including tones, effects, sensitivity, assignments, pitch settings, and other parameters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtensive Effects Processing:\u003c\/strong\u003e Provides dedicated multi-effects and EQ for each part, two Scene MFX processors, chorus\/delay, reverb, Master EQ, and Master Compressor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuitar-to-MIDI Operation:\u003c\/strong\u003e Converts compatible divided-pickup performance data for controlling computer instruments and external MIDI sound modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB Audio and MIDI:\u003c\/strong\u003e Connects directly to a computer for DAW audio recording, MIDI transmission, sound editing, and re-synthesis workflows.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpandable GK System:\u003c\/strong\u003e Supports GK-5 and GK-5B pickups directly and can interface with compatible legacy 13-pin GK equipment through optional converters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eZEN-Core Sound Engine with Four Tones Plus Rhythm\u003c\/h3\u003e\n\u003cp\u003eThe GM-800 brings BOSS guitar synthesis into the ZEN-Core ecosystem. Four independent Tone parts can be layered, split by string, or assigned to selected fret ranges, while the fifth Rhythm part provides acoustic and electronic percussion. The internal library includes at least 1,200 preset tones and 70 preset drum kits, plus storage for 256 imported tones.\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced Serial GK Tracking\u003c\/h3\u003e\n\u003cp\u003eA compatible Serial GK divided pickup sends individual-string information to the GM-800 through its 1\/4\" TRS GK input. Dedicated tracking processing analyzes pitch and playing dynamics for responsive synthesis, while settings for velocity response, pitch behavior, sensitivity, alternate tuning, individual strings, and fret regions allow the system to be tailored to different instruments and playing styles.\u003c\/p\u003e\n\n\u003ch3\u003eScene-Based Performance Workflow\u003c\/h3\u003e\n\u003cp\u003eEach Scene stores a complete collection of performance settings rather than a single tone. Tone selections, part levels, string assignments, effects, sensitivity, control assignments, and other parameters can be recalled together. The GM-800 provides 150 user-configurable Scene locations, with 100 populated with ready-to-play sounds from the factory.\u003c\/p\u003e\n\n\u003ch3\u003eDeep Multi-Effects Processing\u003c\/h3\u003e\n\u003cp\u003eEvery Tone and Rhythm part has its own 93-type multi-effects processor and dedicated EQ. Two additional Scene MFX processors can operate in serial or parallel, while seven reverb types and nine chorus\/delay types handle ambience. Master EQ and compression provide final system-wide shaping before the outputs.\u003c\/p\u003e\n\n\u003ch3\u003eFootswitch and Expression Control\u003c\/h3\u003e\n\u003cp\u003eFour built-in footswitches provide Scene Down, Scene Up, CTL 1, and CTL 2 operation. The two rear control jacks can each accept an expression pedal or support two compatible footswitch controls, expanding hands-free command over parameters such as hold, pitch bend, Tone selection, effects, and other assignable functions.\u003c\/p\u003e\n\n\u003ch3\u003eUSB Audio, MIDI, and Computer Editing\u003c\/h3\u003e\n\u003cp\u003eThe USB-B computer port supports high-speed USB audio and MIDI, allowing GM-800 sounds to be recorded directly into a DAW. Guitar-to-MIDI data can control software instruments, and the ZEN-Core engine can operate as a standalone MIDI sound module. BOSS Tone Studio provides detailed Scene editing, tone organization, sensitivity adjustment, and librarian functions from a computer.\u003c\/p\u003e\n\n\u003ch3\u003eSerial GK and Legacy GK Expansion\u003c\/h3\u003e\n\u003cp\u003eThe GK input connects directly to compatible GK-5 guitar and GK-5B bass divided pickups using an optional BGK Serial GK cable. A dedicated GK output can pass the divided-pickup signal to another compatible Serial GK device. Optional GKC-AD and GKC-DA converters integrate compatible equipment that uses the earlier 13-pin GK connection.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical
