Hoping for some help identifying this guitar I scored for $20 over the weekend. With the homemade pickguard/bridge cover and radio knobs I thought it might be a 70s MIJ tiesco or guyatone. I posted pics to a FB group for vintage MIJ guitars- but when I removed the bridge cover I found a very 50s Fender bridge. People started chiming in and they think maybe 52/53 real deal that’s been refinished. I thought the bridge pickup was working since I got sound with the blade in that position, but unfortunately it’s not passing a signal. The neck pickup is active in all 3 positions. Is this 52 blend wiring? Any help confirming it’s real as well as the year would be awesome!
