Boss GT-1000 Firmware V4.0: Three New X-Amps and Six Bass Models
Boss’s GT-1000 Firmware V4.0, released in 2024 as a free update, adds three new X-Amp types (X-ULTRA, X-OPTIMA, X-TITAN) and six bass amp models using the company’s MDP (Multi-Dimensional Processing) technology. X-ULTRA delivers a classic British stack with modern multi-stage gain, X-OPTIMA uses adaptive frequency shaping for transparent dynamics, and X-TITAN is optimized for aggressive metal tones with surgical low-end control. These additions significantly expand the GT-1000’s versatility for both guitar and bass players.

MDP Technology
Boss’s Multi-Dimensional Processing models the complex interactions between gain stages, tone stacks, and power sections that give real amplifiers their dynamic response. Unlike traditional modeling that captures frequency response at a fixed setting, MDP recreates how the amp’s character changes as you adjust gain, volume, and EQ, providing a more realistic and responsive playing experience.
Who Should Buy the BOSS GT-1000CORE Firmware v2
If you own a GT-1000CORE, this firmware update is a must-install. The v2 update brings significant improvements to amp modeling accuracy, adds new effect types, and refines the overall user experience. Players who use the GT-1000CORE as the centerpiece of their pedalboard or in a studio rack setup will benefit from the expanded tonal options. Since it’s a free update, there’s really no reason not to grab it — especially if you’ve been wanting more flexibility from your existing patches and signal chains.
