Hi!
I need help dating a 1960's J-50. (My feeling is that it is a1966.)
It has round shoulders, the smaller nut width, plastic adjustable bridge, and the serial number is 854333. The pickguard is missing.
I guess the main confusion for me is the plastic bridge, that I though was gone by -66.
Unfortunately someone also installed a pick-up with knobs and all in the mid 70s, but that's a different story...
Any help would be very appreciated!
