Maple top, back and sides, set one-piece mahogany neck. Two Gibson humbucking pickups: the powerful Gibson neck humbucker, and a smaller mini-humbucker at the bridge. 30 1/2 inch scale.
The Gibson EB2D was introduced in 1966, at a time where bass sales were rising rapidly. EB2D signifies double pickups: the EB neck humbucker of the regular EB2, and an EB mini-humbucker towards the bridge.
By 1968 EB2 sales had peaked and the hollow-bodies were losing ground to the solid-body EB0 and EB3 basses; to be phased out completely by the early seventies. 1968 saw the shipping of exactly 700 EB2D basses, 461 in Sunburst, and 239 in Cherry. This was Gibson's top of the line bass at the time, and their most expensive. Recommended retail price was $470, compared to EB2: $425; EB3: $365, EB0: $259.50, Melody Maker bass: $227.50.
Other hardware is essentially the same as equipped on other EB basses: the Gibson two-point tune-o-matic bridge with chrome cover, and under-bridge mute, and Kluson 538 machine heads. But note the rather interesting design on the scratchplate. Gibson did not use it for long, or seemingly on many basses, as example are comparitively uncommon.
