The Thunderbird Bass, first issued from the legendary Kalamazoo factory in 1963, was for a time the only bass available from Gibson or Epiphone. But really, what else could you need? The Thunderbird’s unique “reversed” zig-zag body design and equally distinct headstock was the brainchild of legendary automotive designer and visionary Ray Dietrich who was enlisted by the Kalamazoo factory to bolster the electric guitar line and help solidify the factory’s eminent rank among solidbody electric guitar manufacturers. The Thunderbird bass was quickly embraced by rock and rollers in the States, the UK, and Europe and today, is still the ultimate rock and roll low-end machine. Building upon the long-term success of the classic Thunderbird, Epiphone introduces the Thunderbird™ IV.
