It gives guitarists a way to create synth, modeled guitar, bass, and conventional guitar sounds from one performance setup. The included GK-3 pickup captures each string separately for the GR-55’s polyphonic processing.\u003c\/p\u003e\u003cp\u003eDesigned for players who want sounds beyond a conventional pedalboard, the GR-55 can layer up to four sources: two PCM synth tones, one COSM modeled tone, and the normal guitar pickup signal. This lets a guitarist combine familiar guitar attack with piano, organ, string, pad, bass, or synth textures. It is suited to live performance, home recording, sound design, and MIDI-based music production workflows.\u003c\/p\u003e\u003cp\u003eThe sound engine combines two PCM tone generators with COSM guitar and amp modeling. Its PCM library contains 910 tone types, while modeling provides separate selections for guitar and bass modes. Editable patches, category-based sound access, and a graphic LCD help players move from ready-made sounds to more detailed programming.\u003c\/p\u003e\u003cp\u003eThe GR-55 provides dedicated processing for effects and amp-style tones, including multi-effects, preamp, modulation, delay, reverb, chorus, and EQ selections. Its 24-bit conversion and 44.1 kHz sampling support a detailed digital signal path for the GK pickup, normal pickup, and output stages. An onboard looper expands the unit’s use for practice and live layering.\u003c\/p\u003e\u003cp\u003eFor system integration, the GR-55 includes stereo outputs, a dedicated Guitar Out, headphones, MIDI input and output, USB computer connectivity, and a USB memory port. The computer USB connection supports MIDI and audio communication, while the USB memory port plays compatible WAV and AIFF files with foot control. The included GK-3 pickup and 5 m GK cable provide the key connection between a compatible electric guitar and the processor.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Source Layering:\u003c\/strong\u003e Combine two PCM tones, modeled tone, and normal guitar signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGK-3 Pickup Included:\u003c\/strong\u003e Provides divided-string sensing for compatible electric guitar installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e910 PCM Tone Types:\u003c\/strong\u003e Access pianos, organs, strings, synths, and more.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCOSM Modeling:\u003c\/strong\u003e Create modeled guitar, bass, synth, and amp sounds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB Audio and MIDI:\u003c\/strong\u003e Connect to a computer for audio and MIDI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoot-Controlled USB Playback:\u003c\/strong\u003e Play WAV or AIFF files from USB memory.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GR-55 uses a floor-oriented design with an integrated expression pedal, foot controls, a 240 x 64-dot graphic LCD, and rear-panel connection points for guitar, audio, MIDI, USB, and power. Roland does not publish a chassis-material specification, but the layout is designed to keep patch selection, expression control, and performance functions within foot reach. The unit measures 405 mm wide by 244 mm deep and has a maximum height of 106 mm when the expression pedal is moved to its minimum position.\u003c\/p\u003e\u003cp\u003eInstall the included GK-3 divided pickup on a compatible steel-string electric guitar, then connect it to the GR-55 GK IN using the included 5 m GK cable. A conventional guitar pickup alone cannot directly provide the separate-string signals required for GR-55 synth and modeling operation. Connect the OUTPUT L\/MONO and R jacks to a full-range amplification or recording system, use GUITAR OUT when routing the dry guitar signal separately, and connect USB to a computer or supported USB flash memory as needed.\u003c\/p\u003e","brand":"Roland","offers":[{"title":"Default Title","offer_id":45669335466054,"sku":"GR-55GK-BK","price":1044.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61B_i5iWGGL.jpg?v=1784491839","url":"https:\/\/audiowatt.store\/products\/boss-gr-55gk-bk-guitar-synthesizer-with-gk-3-pickup","provider":"Audio Watt Store","version":"1.0","type":"link"}
