I will go ahead and share my Carvin experience, since it will indirectly answer your question, or whatever...
When I was shopping for a bass to own for a long time I wanted something that was as tonally diverse (and as well built as possible) as I could get for a reasonable price. I loved the Ernie Ball sound, but the price tag and one pickup thing made me shy away. So here's Carvin, with a reasonably priced bass, built to MY specs, that I can play for years and not need another one. I thought to myself "I can get a huge sounding humbucker in the bridge and a j pickup in the neck that are blendable for around half of what I would pay for an ebmm or an American made jazz? Sign me up!" Carvin makes incredibly flexible and workable instruments that sound great and look great, but...
My bass shipped without the screws that hold the battery box down. Not a huge deal, the holes were there, just no screws. A quick call solved the problem. They mailed me the proper screws. Also, my nut came loose after a while, which caused some interesting issues to say the least. A new nut and some epoxy solved that. Carvin is absolutely awesome for what they are: A company that will make a bass to your exact specs for the least amount of cash. It will be beautiful, (if you pay for fancy woods and stuff) and it will sound pretty great. Will it have the attention to detail and signature sound of a more expensive custom made bass? No. They totally oversell that aspect of their company, and it mostly doesn't deliver. They come close, but not all the way.
Carvin makes a product that you can gig with and be incredibly flexible with, will not cost more than your child's education, and will look good doing it. It may not have the panache, flair, or sound that high end basses have, but it will get you through.
To me, Carvin sells a product that will be versatile and VERY workable. Is it special, truly special? Not really. I love my Carvin, but it has always been a tool, not a piece of art that speaks to me.
This truly is a debate that has no winner. Is an American made fender worth a grand + more than an affinity squier? Should we all be playing on $100 washburns because no one but us can tell the tonal difference? What does any of this mean? LIFE IS MEANINGLESS!
