The Epiphone Newport bass (EBS) was a Gibson Kalamazoo made instrument available between 1961 and 1969. The Newport's short 30.5 inch scale length and light weight make it a very comfortable instrument to play. When first introduced the Newport had a symmetrical mahogany body, with two per-side open-book style head-stock. In 1964 the lower body horn was shortened, the pickguard enlarged and the head-stock changed to a four-in-a-row bat-wing design. The Epiphone Newport's design owes a lot Gibson EB0 and the Newport has a Gibson EB0 mini humbucker and similar bar bridge
There was a rare two pickup Newport Deluxe model (EB-D) which was made until 1964 - when it was replaced by the Embassy Deluxe. There was also a rare six string Newport (EB-6) and even one with a built in fuzz tone effect (EB-SF).
The Epiphone Newport was reintroduced in the mid to late 1970s as a Japanese made model for the Japanese domestic market. This model had the later body style combined with the early two-per-side head-stock and two pickups: a double-coil staple-pole pickup and a mini humbucker.
