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 & 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. Custom colors available.
