Hi TB! I'm looking at upgrading from my current bass, which has served me very well for years, to something a little nicer. I was looking at an Upton, probably a flat back (6-8k or so), but had some local luthiers tell me I could do better on the used market in that price range (one bizarrely told me to stay away from Upton, which seems to contradict all the good things I've heard). Most of the things I see in my price range, at least that catch my interest, are older German basses, though I'm not sure which are from factories and which are from a shop. I mostly play jazz but do play in a community orchestra. Any thoughts on the value of an Upton v. something vintage? I know they have the 100% trade in when you move up, which is a big plus, but maybe the perfect bass is out there being unloved.
