The impressive DSP engine delivers on-demand power for all available effects, so you’ll never worry about running out of processing while building sounds.

The Hub of Your Home Studio

GT-1000CORE is a perfect companion for recording and playing at home. It’s a multi-channel USB audio/MIDI interface for flexible DAW production and efficient re-amping. Recording mode allows you to choose from a variety of built-in speaker and microphone types, and it’s also possible to import 16 of your favorite WAV-format speaker impulse responses. The onboard looper is a great tool for practice, building sounds, and developing ideas. And with BOSS Tone Studio’s intuitive user interface, it’s easy to craft sounds on a Mac or Windows computer.

AIRD: A Revolution in Digital Amp Processing

GT-1000CORE harnesses BOSS’s breakthrough AIRD technology for a new level of performance, flexibility, and usability. AIRD is an evolution of the comprehensive Tube Logic concept behind the Katana, Waza, and Blues Cube amplifiers, adapted to provide consistent response across the many different scenarios where an amp processor might be used. AIRD enables GT-1000CORE to smoothly flow into any creative setup, providing great tone and natural tube amp feel with minimal adjustments. A large selection of AIRD Output Select types let you tailor the sound for any destination, whether it’s a guitar amp input, a power amp driving guitar speakers, or a full-range monitoring system—or all of them at once. AIRD is fully integrated into GT-1000CORE’s amps at every level, so you’ll always experience their authentic sound and response, no matter what you’re plugged into.

Premium Amps and Effects

GT-1000CORE is loaded with expressive guitar amplifiers, all meticulously crafted with AIRD. There are BOSS original amps suitable for all guitar styles, plus famous tube amps from coveted vintage combos to modern high-gain heads. A massive range of effects options are also on board, including BOSS classics, retro stompboxes, MDP effects, and advanced algorithms from the BOSS 500 series. Multiple series and parallel routings are easy to set up with the intuitive interface. And with the clever Stompbox feature, commonly used amp and effects settings can be adjusted across multiple patches at once.

Top-Flight Bass Processor

GT-1000CORE is a bass processing powerhouse in a grab-and-go package. Three AIRD bass preamps are provided for shaping your core tone, and eight different overdrive/distortion effects are available for additional color. There’s an MDP bass compressor too, plus chorus, flanger, touch wah, and many other effects specially tuned for bass. And with GT-1000CORE’s versatile effects and output routing, you can deliver optimized sound to a stage amp or PA mixer—or both at once.
