Crunch Lab Bridge Model [DP228] (Cream/Standard-Spaced) John Petrucci, a leader in the progressive metal genre since the late 1980s, has been using DiMarzio pickups for many years. The runchLab is the latest model developed in collaboration with Petrucci. He has been using these pickups since the production of Dream Theater's 10th album, "Black Clouds & Silver Linings." He considers these pickups to be the best he has used in live performances and recordings to date. They have a big, tight sound without any muddiness. Technical Notes: While similar in appearance to the D-Sonic, the internals are very different. The Crunch Lab is louder, with deeper highs and a more open midrange and low range, which is crucial when playing chords with a high-gain amp. John Petrucci is such a fan of the Crunch Lab that he installs it in nearly all of his guitars, including his baritone, with the solid bar facing the neck, regardless of the tuning of the guitar.
