The DiMarzio DP228 Crunch Lab Humbucker Guitar Pickup designed for the bridge position is the result of a collaboration between John Petrucci and DiMarzio. Petrucci used it throughout Dream Theater’s tenth studio album, ‘Black Clouds & Silver Linings’, and he swears it is the best live and studio sound he has ever had. The DiMarzio Crunch Lab pickup is defined, powerful and very open sounding.
The DP228 Crunch Lab has a physical appearance identical to the D Sonic, but the internal design is a lot different. It’s louder, and the highs have more depth. The lows and mids are more open, and this is crucial for playing chords with body and presence through a gained-out amp. The voicing of the pickup is also different enough to the point that John prefers the Crunch Lab to be installed in almost all of his guitars with the solid bar toward the neck, regardless of the guitar’s tuning.
