I’ll add my 2¢ (valued at 1¢ at this point):As there seems to be a community that really loves them, are there particular features/finishes/years that are particularly desirable? I’ll be honest and say that the body styles and headstock puzzle the heck out of me. I’m not enamored with their appearance, but I’m wondering if they’r an acquired taste kind of thing…it’s not a “love at first sight” kind of thing for me. The look mentally and physically awkward- but still I hear a small voice inside my head that says “hmmm…could be interesting”.
I have six standard (reverse) Gibson ‘birds, one short scale Gibson ‘bird and one first year (2017) Epiphone VP. Not one is a “non-reverse”. And at the moment not one of the Gibsons contains the original TB+ ceramic pickups. I did recently get some trim rings to fit the TB+ pickups so I may put some back into the one Gibson ’bird (1995) that still has black hardware. All of the other Gibsons are now wearing nickel or chrome hardware. I personally love the look with the nickel or chrome pickups with trim rings and I prefer the sound of Alnico V pickups.
The Epiphone VP I have is all original still and is a fantastic bass that I snagged for $350. It is the least “bassy” of all of them but it has its place and gets played frequently in my three pice band. It’s the biggest feeling one with the oversized headstock, which I guess is meant to emulate the originals from the ‘60’s? But it’s still a good introduction to the Thunderbird world at a low price. But it does not sound like a much more common Gibson from the ‘90’s to now.
Further, I have a number of P-basses and J-basses from the ‘70’s, as these were my favorites for years. One struggle I always had as a hard rock player was getting the notes played on the thinner strings to push through while playing with loud(er) guitar(s) and hard hitting drummers. The Thunderbirds solved this problem completely. They have a nice full warmup tone that “pushes” through in the mix.
