DiMarzio LiquiFire DP227 One thing has stayed consistent throughout John Petrucci 's long and successful career: the DiMarzio pickups in his guitars. John has been pushing the envelope of progressive metal since the late eighties, and the DiMarzio LiquiFire Neck Model resulted from our most recent collaboration with John. He used it throughout Dream Theater 's tenth studio album, "Black Clouds and Silver Linings".
John swears this is the best live and studio sound he has ever had. He wanted a neck pickup with a flowing, singing solo tone when used with a heavily overdriven amp and a clear chord sound with a clean amp setting.
Recommended For: Neck. Can also be used in bridge position.
Tech Talk: Since the mid 1990s, John 's neck pickup sound has been based on either the standard Air Norton or the custom version in his Ernie Ball guitars. The LiquiFire has several significant differences. Its treble response is warmer and smoother while bass response is tighter and brighter. The total sound has a more focused voice which works equally well for highly overdriven solos and complex, clean chords.
