Built in the U.S.A. The JP Majesty Precious Metal 6 is John Petrucci's first neck through signature guitar by Ernie Ball Music Man. The Majesty features a mahogany neck through a basswood body with a polished ebony fretboard. What appears to be a carbon fiber shield on top of the body is actually laser etched maple. The lower cutaway of the body provides incredible access to the upper frets, made of stainless steel. A piezo equipped custom Music Man tremolo is capable of generating acoustic tones while the DiMarzio Illuminators and 20dB gain boost provide searing tones for leads.
