The PGMM31 features a poplar body bolted to a 22.2″ scale maple neck with a reversed headstock and a 24-fret maple fretboard with black dot position markers. Components include dual Ibanez Infinity R humbucking pickups and a fixed bridge. As with the other Paul Gilbert signature models, the PGMM31 features painted on “f holes” to help camouflage the controls, which consist of only a master volume and a 3-way lever pickup selector. For 2019 the 3-way switch was replaced with a 5-way offering coil-split options in positions 2 & 4.
