AIRD: A Revolution in Digital Amp Processing

GT-1000CORE harnesses BOSS's breakthrough AIRD technology for a increased 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, offering exceptional sound processing and versatile DI capabilities 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.

"Boss GT 1000 Core"

Overall:

(see rating details)

Verified Customer zZounds has verified that this reviewer made a purchase from us.

After purchasing - and being mostly disappointed with - modelers from other brands I was hesitant to spend the considerable sum on the GT 1000 core. But after extensive review of specs and sounds on Youtube and a good deal from zZounds I went for it. I purchased it solely for the presets because my past ventures into programming haven't been good. I haven't gotten through all of them yet but unlike all the other units I've tried that have only a very few actually useful preset patches, the GT-1000 has a considerable number of them, going straight into my studio console, flat EQ, no additional processing or effects. The verdict so far: I don't think I'll ever again have to use a microphone to record most guitar parts. Additionally, Boss has kept the noise levels surprisingly down on the hard overdriven patches, also unlike the other units I've mentioned. The only drawback I've found - and it isn't major - is that there is a dearth of straightforward Fender clean sounds without effects. I'm sure there's a way in the internal programming to deal with that but I haven't found it necessary yet. The effects are pristine - very well done. All-in-all, worth the money.
