Thank you for viewing. This is the pickup originally installed on the bridge side of a Music Man John Petrucci signature model 7-string guitar that I owned. It's a custom part made specifically for Music Man, not a commercial model, so it's rare and not often found on the used market. It is fully functional. It will be shipped in a case from a different model. DiMarzio John Petrucci Music Man 7-string guitar 7-String Bridge Pickup Music Man John Petrucci 7 (JP7)
