I've been playing a T-Bird for 30 years and I just never got the rap about neck dive (or maybe I've been in denial all these years?). My right forearm sits on the body and counteracts the weight of the neck (and my strap button is in the original location). Its always been a non-issue with me. You do need to have straplocks if you use the original strap button location though.......
So, here we have a testimonial from a T-bird player of 30 years. Doesn't look like any naysayers have bothered to read it.
heatheroo's experience speaks for itself. You can't call something a design flaw just because YOU don't happen to like it, or can't deal with it. Some people here (at Talkbass, not this thread) have said "bolt on construction is a design flaw", and "non-angled headstock is a design flaw", and the neck dive claim is equally silly. Let's see, what else: "roundwound strings are rough on your fingers, that's a design flaw". Might as well cite any neck profile, string spacing, or scale length that makes your hand uncomfortable.
I could do my job just fine with a neck-divey bass -- therefore, it is NOT a design flaw, even though I *prefer* to avoid basses with neck dive.
