Ernie Ball Music Man

collapse expand iconDescription

The JP12 7 is the collaborative effort between John Petrucci and the Music Man research and development team. It features a long list of top appointments, including an extra slim profile mahogany neck, with a flatter 20" radius ebony fretboard and medium jumbo stainless steel frets. This particular run has a different body wood. It features the toneful combination of an African mahogany body with a quilted maple top.

Controls include two three-way toggles perfectly wired for the Custom DiMarzio LiquiFire and Crunch Lab humbuckers, in addition to a Music Man/Fishman piezo system bridge pickup and a Custom John Petrucci Music Man floating tremolo system made of chrome-plated hardened steel with solid steel saddles. And the Schaller M6-IND locking tuning machines keep the JP12 perfectly in tune under even the most punishing circumstances.
