The MX4 is a Maxxas series semi-hollow body electric guitar model produced by Ibanez in 1988. It is also referred to in some materials as the MX-4.
The MX4 features a semi-hollow, thin-edged, sculpted maple body bolted to a color-matched painted maple neck with a 29-fret rosewood fingerboard with oval position markers. It has only a single humbucking pickup and a fixed bridge. The lack of a neck pickup and the extra deep cutaway on the lower horn allow access all the way up to the 29th fret.
The MX5 is a similar model with a synchronized tremolo bridge.
