The upper fret access is much better isn't it? You've got me thinking about a pink Thunderbird now...
Seriously though @NancyJohnson, you seem to be getting a bit angry about all this. Only one person on here has replaced their truss rod cover. Nobody's trying to get one over on Gibson . There's just a lot of us happy that there's finally an affordable Thunderbird that does what we want. And does it extremely well to boot.
I've played and owned several Thunderbirds, including Gibsons. Forgive me if I'm wrong, but you don't appear to have tried these Epiphones either.
