The JP157, based on the seven string version of the Ernie Ball Music Man JP15, features sleek styling, and seductively good looks with its highly figured, Quilted Maple top. Ergonomically arranged in-line controls include a 3 position pickup selector, Volume, and Tone VR controls. Additionally, JP157 features an Active push-push 12dB circuit boost on the Volume control, allowing the player ultimate soloing power at their fingertips. This Active Circuit is powered by a 9V battery that loads into an easily accessed compartment on the rear of the instrument, and requires no tools, making battery changes user friendly and quick.
Accurate intonation, smooth operation and excellent tuning stability come courtesy of the combination of Locking Tuning Machines and the Sterling By Music Man designed Modern Tremolo. This premium, full floating tremolo system is featured on most John Petrucci Signature Series instruments, and allows for full dives, 2 step pulls, and is exceptionally responsive to flutter effects, all while maintaining accurate tuning.
The Locking Tuning machines are arranged in a 5+2 manner on the headstock, giving positive, in line string pull over the nut. String changes are easy with a slight turn of the locking wheel mechanism located on the rear of each tuning machine. Johns’ signature is also proudly featured on the face of the headstock.
