I don't agree that its ugly. Sheldon doesn't do ugly. But I never had a thing for the Gibson Thunderbird back in the day, so I'm not jonesing for a D-Bird. My current obsession is the NG3 6 string.
I think my comment is more on the body style/design in general, and less about the D-bird itself. I bet if I played one, I'd love it, but that wouldn't change how I felt about the design.
I always appreciated it's unique style and voice, but I'm strictly a praise bassist these days and don't need the 'monster' tones. Also, for me to buy a different Dingwall, I'd have to part with one or two, and I'm too happy with the ones I have at hand.
