The comparisons to women concerning instruments are always the best for some reason lol...it's mainly because they're so true.
I realize there are a lot of great boutique instruments out there, but it's sort of like online dating. She may have a wonderful bio, look gorgeous, and have all the right tastes/interests...but the internet can't tell you if she has bad breath, is a horrible cook, or sings awfully while shes listening to music. There are some things you just have to experience in person. If you feel like risking the money, the time, and paying for restocking/return fees then try some boutique instruments that you pick out on the web. I've personally had better experiences with basses I've been able to hold myself before I bought. Finding a great boutique bass isn't
impossible by any means, they are usually expensive for a reason (they are super well-made), but it's a shot in the dark and you may have spent more than you wanted just to say you have a fancy wood top. For some people brazilian rosewood is a must on their instruments, where some people are fine with indian rosewood instead. It boils down to taste at the end of the day.
What kind of amp do you have? I think that it's better to have a
balanced rig as opposed to it being "lop-sided" if you will. Playing a $7,000 Wal through a 15w Acoustic combo is not going to do that bass any justice. Spend $2-3k of your budget on a nice bass and the rest on a good bass rig. Be it Mesa, GK, Markbass, or Eden for solid state...or Ampeg, Fender, Traynor, Orange, Mesa, or Peavey for tube stuff, you could get a monster rig that will define your sound just as much (if not more) than a pricey bass alone can. The most expensive bass guitar in the world will still need an amp
