Mid-1965 saw a total redesign of the entire Gibson Firebird series of guitars, switching to a more traditional "non-reverse" body shape, much simpler construction, some pickup and hardware changes, and the introduction of far more custom colors than were available on the original run.
The early Firebirds used a complex neck-through-body design, but the new models went with a more traditional set-neck and were significantly lighter, easier to build, and came in at a lower price than the first Firebird design.
The "Non-Reverse" Firebird III features a trio of P-90 pickups, short vibrola tailpiece, and an unbound neck with dot inlays. While Sunburst was the standard, most common finish, vibrant custom colors can be had for a premium price.
Note: A large number of Firebirds have had broken headstocks repaired -- for pricing purposes, we encourage all sellers (and edit when necessary) to use "Good" condition or below when these guitars have had repaired headstock cracks or breaks.
