Hey folks, I have an azureglo rick with a replaced output jack. I think the finish dates it to 79 - 85, but it has pots from 1974... I understand that the bridge pickup position changed mid-1974-- does anyone know the distance of the center of the bridge pickup from the 20th fret pre-1974/ post 1974? Mine appears to be 6.5 inches... Any help in dating this bass through other methods would be greatly appreciated. Thanks!
