http://www.ebay.com/itm/1979-Gibson-Thunderbird-Bass-IV-Bicentennial-Sunburst-Finish-Player-/281137995268?pt=Guitar&hash=item4175215e04 I just saw this and thought the neck heel looks waaay darker than it should, like maybe there was a repair and then black over spray. I know there was a repair around the nut area. I am comparing this to my sunburst '76 T-bird, and mine has a transparent back finish. Maybe they shot them like that. Anyone have a '79 like this? Here is a shot of my '76 neck heel.
