DiMarzio John Petrucci Signature Model Crunch Lab 7 Humbucker Pickup – Black

DiMarzio Joe Satriani Signature Model PAF Joe Humbucker Pickup – Black

Bring powerful, precise and articulate tone to your seven-string electric guitar with the DiMarzio DP708BK Crunch Lab 7 John Petrucci Signature Humbucker Pickup. Developed in collaboration with Dream Theater guitarist John Petrucci, this high-output bridge pickup delivers tight low frequencies, expressive midrange and exceptional clarity for progressive metal, hard rock and demanding high-gain performances.

Introduced in 2009, the Crunch Lab 7 was developed during the recording of Dream Theater’s album Black Clouds & Silver Linings. Its design reflects Petrucci’s preference for a full-bodied guitar sound that remains focused and well-defined, even when playing complex chords through heavily overdriven amplifiers.

The pickup features a distinctive asymmetrical pole-piece arrangement, combining a continuous metal bar with individual pole pieces. Although visually similar to the DiMarzio D Sonic 7, the Crunch Lab 7 has a different internal design that delivers stronger output, deeper highs and a more open low-midrange response.

Equipped with a ceramic magnet, the Crunch Lab 7 provides a sharp, immediate attack with excellent note separation. Its manufacturer-rated 410mV output delivers the power needed for aggressive rhythm performances while maintaining the articulation required for fast picking, intricate riffs and expressive lead passages.

Unlike pickups that rely on exaggerated bass frequencies, the Crunch Lab 7 is voiced for a controlled low end. This makes it particularly effective for seven-string instruments, where lower notes can become muddy when combined with heavy distortion. Its balanced response allows complex chord voicings to retain body and definition without sacrificing punch.

The pickup’s installation orientation also influences its tonal character. With the solid bar facing the neck, it produces the fuller, balanced response favoured by John Petrucci. Reversing the pickup with the solid bar facing the bridge creates a brighter response, allowing players to experiment with different tonal characteristics.

Featuring four-conductor wiring, the Crunch Lab 7 supports coil splitting and parallel humbucking configurations when installed with compatible guitar electronics. Its passive construction requires no battery and integrates with conventional electric guitar control systems.

Designed specifically for the bridge position of compatible seven-string electric guitars, the Crunch Lab 7 pairs naturally with the DiMarzio LiquiFire 7 Neck pickup for a versatile combination of rhythm, lead and clean tones.

Finished in classic black, the DiMarzio Crunch Lab 7 DP708BK is an excellent choice for guitarists seeking powerful high-gain performance, precise low-string articulation and expressive playing dynamics in a seven-string humbucker.
