|Tilt Joint on a RG770DX|
The neck joint is the point at which the neck attaches to the body of the guitar. A screw plate is used to secure the joint, but unlike classic bolt-on models such as the Fender Stratocaster the actual heel is tilted toward the bottom to create a thinner joint which eases access to the upper frets.
It was replaced by the even thinner All Access Neck Joint on most Ibanez models.
It was used on RG type guitars from 1987 until 1993. Almost all RG models from 1994 and later have the AANJ (with the RG170 being one exception). The Tilt Joint did reappear on the 2007 and 2008 RG reissues and on the 2009 PGM100 Paul Gilbert Model reissue. Paul Gilbert also requested it on his 2009 PGM401 model. Pre-AANJ Ibanez JEM models have the thinner Cutaway heel.
