GT-1000 CORE

The Sound Core of Your Creativity

The GT-1000CORE is a guitar/bass effects processor that combines flagship-grade sound quality with exceptional flexibility. Powered by the same high-performance DSP found in the flagship GT-1000, it delivers premium audio quality throughout. BOSS's cutting-edge AIRD technology reproduces the sound and feel of a real tube amp, while the onboard preamps and effects total over 140 types — with 24 effect blocks, including two preamps, usable simultaneously. Compact in size yet equal to the GT-1000 in sound-shaping capability, the GT-1000CORE is ready for everything from rehearsal to the main stage. Extensive I/O and control expandability also make it a natural hub for any signal chain.

More Possibilities for Your Pedalboard

The GT-1000CORE brings new potential to any rig, from a compact, minimal pedalboard to a large-scale effects system. Stereo-capable I/O lets you place effects freely before and after any point in your chain. The two SEND/RETURN loops open up flexible integration with external effects, 4-cable method amp connections, and direct outputs to PA or recorder. The CTL jack on the side panel works as both input and output — connect additional footswitches or expression pedals for real-time control, or link to an amp for channel switching. TRS MIDI IN/OUT adds seamless integration with external MIDI devices. Operationally, you can choose between MEMORY mode for instant patch recall and MANUAL mode for direct, hands-on effect control — whichever suits your playing style and setup best.

The Ultimate Powerful Stomp

Portable in size but uncompromising in sound, the GT-1000CORE delivers professional-quality performance in a single unit. All 24 effect blocks — including two preamps — run simultaneously, and the powerful custom DSP engine lets you build your ideal tone without worrying about processing limits. Store up to 250 user patches for a wide range of sounds, always ready to call up instantly. Delay carry-over and ultra-fast patch switching ensure the highest level of performance under live conditions as well.

The Heart of Your Home Studio

The GT-1000CORE is equally at home in your practice room or studio. The multi-channel USB audio/MIDI interface connects directly to your DAW for recording and re-amping. Set OUTPUT SELECT to RECORDING mode and you can use the built-in speaker and mic simulations alongside imported external IR data for an even wider palette of tones. The built-in looper is useful for daily practice and phrase ideas, and also lets you reference your tone in real time while making adjustments. BOSS TONE STUDIO (Windows/Mac) gives you a full overview of all your settings and makes intuitive editing easy.

Cutting-Edge Technology That Redefines Amp Processing

The GT-1000CORE's AIRD technology delivers a new level of performance, flexibility, and usability. Building on the Tube Logic technology found in WAZA AMP, KATANA AMP, and Blues Cube, AIRD reproduces the complex interactions between components that occur when a real tube amp produces sound — from your input all the way through to your amp or PA. Simply select the optimal AIRD OUTPUT SELECT setting for your output device, and experience authentic, responsive playing feel wherever you plug in.

Premium Amps and Effects

AIRD technology gives the GT-1000CORE's preamp section an expressive, dynamic sound. A wide range of amp types covers every style, from BOSS originals to vintage classics and modern high-gain monsters. The effects library is equally comprehensive, spanning classic stompboxes, BOSS's legendary models, MDP effects, and advanced algorithm-based types. Multiple dividers and mixers in the effects chain let you freely configure series and parallel routing for intuitive sound design. The STOMPBOX function lets you save favorite settings for individual effects — and since STOMPBOX data is shared across all patches, editing a STOMPBOX updates every patch that uses it at once.

A World-Class Bass Processor

The GT-1000CORE also excels as a next-generation bass effects processor. The AIRD Preamp at the core of your sound offers a diverse range of amp types, and combined with eight bass-specific overdrive/distortion types, it covers a huge spectrum of bass tones. Bass-tuned effects include an MDP compressor that responds naturally to your playing dynamics, plus chorus, flanger, touch wah, and more. Using the SEND/RETURN as a SUB OUT lets you send separate signals to your amp and to a PA or recorder simultaneously, adapting to virtually any performance situation.
