Toggle between Memory and Manual modes to recall presets or kick effects on/off, and easily integrate with other stomps via mono or stereo I/O.

And with MIDI I/O on space-saving TRS jacks, GT-1000CORE can control—or be controlled by—other MIDI devices in your rig.

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 provides 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, offering consistent and reliable response in every playing scenario. Your sounds flow smoothly into any creative setup, providing great tone and natural tube amp feel with minimal adjustments. A large selection of AIRD Output Select types 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 the GT-1000CORE 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, advanced MDP effects, and more. 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. A variety of AIRD bass preamps are on hand 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. Versatile effects and output routing options allow you to send optimized sounds to multiple destinations, such as a stage amp and PA mixer.

GT-1000CORE Version 2.0: New X Amps and More

The Version 2.0 update brings even more creative features to the GT-1000CORE platform, including three newly developed high-gain guitar amp types that spotlight the continuing evolution of our advanced AIRD and MDP technologies:

X-Ultra—Inspired by a classic British stack amp modified with a modern multi-stage gain circuit. MDP provides precision control of the clipping in each gain stage, realizing extended dynamic response that’s not possible with traditional analog designs.

X-Optima—With many high-gain tube amplifiers, it can be difficult to strike the ideal tonal balance between chords and single notes. X-Optima features an innovative new gain algorithm that takes full advantage of MDP’s adaptive frequency shaping, providing well-defined rhythm sounds and rich lead tones that sit perfectly in every mix.

X-Titan—This articulate amp type is perfect for aggressive metal styles driven by heavy riffs. MDP delivers sharp, tight sounds on the low strings while retaining fatness and body in the high ranges, making it well-suited for down tunings and extended-range guitars with seven or eight strings.

The update also includes six new bass preamps, two new drive effects, and other enhancements.
