For those wondering about the bridge pickup in John's guitar, in the mid 90's the Dirty Fingers pickup in the bridge position just stopped working. John's tech at the time installed something. John wasn't exactly sure what it was. It sounded different but John said it sounded good enough.
In 2017 John found the original Dirty Fingers pickup in a road case. I asked around and it was suggested that Wade at Motor City Pickups was the guy to see about repairing the pickup. I spoke to Wade and then put him in touch with John. We then sent the pickup off to Wade. He repaired it and sent it back and the pickup was re-installed back in John's guitar.
John was very happy with the results and said it sounded like his guitar again. Wade did a writeup on the process on FaceBook back then.
