The DiMarzio DP228F Crunch Lab is an F Spaced humbucker for the bridge position of your electric guitar. DiMarzio has teamed up yet again with John Petrucci to create this pickup that delivers the best live and studio sound around. John Petrucci even used them on most of Dream Theater's tenth studio album, 'Black Clouds & Silver Linings". This pickup is named the Crunch Lab for a reason. It delivers a tight, fat sound that doesn't get muddy with playing. The louder you go, the more in depth your highs sound. The lows and kids are more open which it a must when playing chords with body through a high gain amp. If John Petrucci has these installed in almost every guitar he owns, you know it's worth every penny. Comes in Black. F Spaced.
