The Music Man John Petrucci 6-string features a sturdy basswood body with a sculpted neck joint for freer access to upper frets, married to a maple neck via five-bolt mounting with an adjustable truss rod. The fingerboard is made of rosewood and features 24 wide, high-profile frets. Outfitted with two custom DiMarzio humbucking pickups designed specifically for Petrucci and the piezo bridge adds bright, natural sustain for clear, high-gain-friendly tone.
