The most notable feature of the AX125 is the Downshifter D-Tuner, which facilitates on-the-fly tuning changes. The AX125 features a mahogany body bolted to a maple neck with a 22-fret bound rosewood fingerboard and dot inlays. Components include dual Ibanez Axis humbucking pickups and a fixed bridge. The AX120 is a similar model without the D-Tuner. The AX125 was discontinued after 2004.
