Ah, see, when I go to stores to try out basses, I'm not there to buy, just to look. By the time I have the money to buy, I generally already know what I want beforehand.
I judge basses based on how they play when I play them, I simply can't tell how a bass is going to be after it's setup, so I judge it right "off the shelf". Then it either plays well or it doesn't. If it does play well, then it's good.
I've noticed Ibanez basses tend to play very well off the shelf. More so than basses by a lot of other manufacturers. MIA Fenders tend to be really nice too.
I have learned though that regardless of price point, all basses are hit and miss. Squier, Fender, Ibanez, EBMM, Modulus, they're all hit and miss. Which is why I don't like the idea of buying basses online (still bought an SX and that turned out to be worth it). I really prefer to try the bass in person (before it's setup) before I buy it.
If the bass plays well before it's setup, it tends to play very well afterward.
Although you can judge that particular bass, if it isn't set up well that shouldn't reflect all basses made by that manufacturer. One EBMM could play horribly since it was on a shelf for a year with stock strings and 200 people playing it. Then the one next to it could be set up properly and give the intended sound. Not saying that you are bashing EBMM, just puting it out there that people can't judge a whole company by 1 bad one.
