The Peavey EVH Wolfgang Pickups were wound by Peavey in Mississippi and consists of a neck humbucker and a bridge humbucker with Zebra covers. According to Jim DeCola who designed the pickups with Eddie Van Halen the specifications of the pickups are the same as the Fender made EVH Wolfang guitar pickups. The DC Resistance are between 13kOhm - 16kOhm. Due to the fact that they used different enamel wire types, the neck pickup actually had a higher impedance than the bridge humbucker (16.22 kOhm on the neck and 13.87 kOhm on the bridge) which is uncommon.
The Peavey operating manual says the following: " The two Peavey humbucking pickups, custom-wound to Edward's specifications, supply optimal output and tonal response. A two-step wax dipping process is used to provide ultra-low noise operation and resistance to microphonic feedback. The pickups are mounted directly to the body, which further reduces feedback at high volume levels and offers enhanced tonal response."
The Peavey EVH Wolfgang Special EXP models did have the same spec pickups but were not made in the US.
