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 rock since the late eighties, and the DiMarzio Crunch Lab Bridge Pickup ensued from Dimarzio"s most recent collaboration with John. Get the sound that the acclaimed Dream Theater guitarist has spent decades perfecting. He used this humbucker pickup throughout Dream Theater"s tenth studio album, Black Clouds & Silver Linings. John swears this is the best live and studio sound he has ever heard, and the name says it all"crunch" is what it"s all about, with a big, tight sound that"s neither muddy nor thin. The DiMarzio DP228 guitar pickup is recommended for the bridge position.Wiring: 4-conductor Magnet: Ceramic Output: 410mV DC resistance: 11.03k ohms Year of introduction: 2009
