 Many of Fender Contemporary Stratocaster and Telecaster models had Fender Japan E serial number prefix at the beginning of their serial numbers but in fact, Fender never produced a line of guitars named the "E series".When CBS sold Fender to its current owners in 1984, there was a transitional period from 1984 to 1987 with limited Fender USA production resulting in mostly Fender Japan and leftover USA made guitars being sold.There are also Fender Contemporary Telecaster models with HSS or HH pickup configurations and switches for selecting pickup options.
