BOSS GT-1000CORE — Flagship Multi-Effects Processing in a Compact Format

The BOSS GT-1000CORE delivers the complete DSP power of the acclaimed GT-1000 flagship in a streamlined, pedalboard-friendly enclosure. Featuring 32-bit AD/DA conversion, 32-bit floating-point processing, and a 96 kHz sampling rate, it represents the pinnacle of digital guitar processing available in a compact unit.

At its core is BOSS's proprietary AIRD (Augmented Impulse Response Dynamics) technology, which models the complex interactive behavior of real tube amplifiers. With over 140 amp and effect types, 185 total effect types, 24 simultaneous effects blocks, and 500 total patches (250 preset + 250 user), the GT-1000CORE provides an entire professional-grade rig in a single unit. Dual send/return loops integrate seamlessly with existing pedal setups.

The GT-1000CORE doubles as a high-quality USB audio and MIDI interface, enabling direct recording and DAW integration. An onboard IR loader supports up to 16 WAV-format speaker cabinet impulse responses. The built-in looper provides 38 seconds of mono or 19 seconds of stereo recording. BOSS Tone Studio software (Windows/macOS) enables deep patch editing and management.
