As someone who's owned what I consider expensive basses (no Foderas or Ritter or anything that crazy but multiple top of the line Warwick's) I personally think there's a few interesting pricepoints where you get a better bang for your money. But really $2k is my limit these days for a main player, $500 for a used beater for a backup or "different tool in the shed" I just feel like there are plenty of basses under $2k that sound great. Ive yet to play any bass I likes more than my dingwall. And I've played high end Warwicks, Roscoes, you name it. A lot of what you're paying for above that is higher labor cost, a name, bigger profits, at the 2k range a lot of the little details like fretwork, the nut cut properly and stuff like that is already good. At the $2k price range no ones using cheap parts. For example the pickups in my ng2 are from dingwall in Canada, Darkglass preamp is no slouch, the hardware isn't great also. Lot of the time you can buy cheap instruments and with a little work and cash improve the sound and feel. You can't polish a turd so to speak, I wouldn't recommends buying basses made out of plywood for example but These days i think a lot of companies have run out of their really old wood. People are willing to spend multiple times as much on an older fender made of wood that's a hundred years old than a new fender or musicman even if they are put the wood through additional drying treatments like musicman does in their factory. Obviously there is a point where craftsmanship and parts take a huge nose dive. But nowadays with most mass produced basses being mostly built by machines the issue with cheap basses is mostly less than stellar wood or cheap parts
