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.
