If you are in Murfreesboro,please IM me and I'll give you my phone # ,I'll be glad to help you find a good bass,,any of the ones u listed are ok basses but like Mollykay said there are a lot of good used basses out there and a bass that has been played more always sounds better than a new one,,You will not find a bluegrass bass at Dustin Williams shop,,he caters to the orchestra and jazz crowd,,he just recently insulted a close friend of mine by calling his 40s American Standard, a cheap hillbilly bass,,,that insults me as well, since ive played A/S basses for a long time.I have had him do a couple of things for me and he is priced quite high,,,In saying that,he will not have to worry about me sending him any more work again.
A good Kay or King might cost you a bit more ,but the value will only go up,, and even a used engelhart will sound so much better than a new one,,hope this helps,,Kent
