All Access Neck Joint on an FGM100 Enlarge sprite

The All Access Neck Joint (AANJ) is a slimmed down neck joint on Ibanez guitars with bolt-on neck mounting constructions. The neck joint is the point at which the neck attached to the body of the guitar. When joining a guitar neck to its body using screws, a substantial piece of wood on the body side is needed to house the screws and keeping the construction 'sturdy'. This neck 'heel' can be a real obstruction when trying to reach the upper frets. As opposed to the more square "traditional" bolt-on neck heels, the AANJ is slimmed down and rounded off for easier upper fret access.

The first Ibanez guitar to feature the AANJ was the 1987 MX2 Maxxas guitar model.
