What DiMarzio pickups did Eddie Van Halen use?
1) In the early 1990s, DiMarzio designed both the neck and bridge pickups for the (now discontinued) famous Van Halen Music Man signature guitar. This was the first ground up guitar design that Van Halen made. (See DiMarzio Remembering Van Halen)
These exact pickups are still available and limited to the USA made Music Man Axis guitar. None of the overseas-built versions of the Music Man Axis guitars have these DiMarzio pickups.
The closest sounding pickups that DiMarzio offers to the Van Halen set are the Air Norton™ for the neck position and either the The Tone Zone® or the DiMarzio® AT-1™ for the bridge position.
2) The reddish color neck position single coil in Eddie’s Frankenstrat is a DiMarzio Fat Strat, later renamed the FS-1™. When Larry DiMarzio first met Van Halen in 1989, the Fat Strat pickup in his guitar wasn’t connected.
3) Both web speculation and Wayne Charvel have said that Eddie used a Super Distortion® in the bridge position of his Charvel guitar, and this was the pickup Van Halen asked Wayne to pot because it had become microphonic in that guitar. (See The History of Wayne Charvel)
