Description
The JP157 is Sterling by Music Man’s take on John Petrucci’s demanding 7-string spec sheet, and it shows in every detail. A mahogany body wears a highly figured flame maple veneer top finished in Island Burst, giving the guitar visual depth to match its tonal range. The roasted hard maple neck and matching roasted maple fingerboard aren’t just for looks – roasting stabilizes the wood and adds a woody snap to the attack, while pearloid JP shield inlays mark the 24 medium jumbo frets.
A 16″ fingerboard radius and 1.95″ nut width keep the neck fast and comfortable for wide-interval runs and chordal work alike, and the dual-action truss rod paired with a 5-bolt neck attachment keeps things locked in tight. The modern tremolo bridge lets you add expressive pitch moves without sacrificing tuning stability, especially with the locking tuning machines doing their job upstream.
Electronics are kept purposeful: HH pickups run through a 3-way toggle, with a single volume and tone knob. That volume knob hides a trick – a push-push switch engages a 12dB boost for solos or leads, no extra pedal required. It ships strung with Ernie Ball 2621 Regular Slinky 7-String strings and comes with a Deluxe Sterling by Music Man gig bag for transport.
