You are right, of course. But there was just a bunch of negative comments about a bass the OP was happy with and about something he can't undo, so it only served to make him feel bad.I see nothing wrong with offering ones opinion, as long as it is done in a respectful manner. No thread has to be strictly a "fanboy" thread over a subject.
I have no problem offering opinions (I've got LOTS) but it should be done as you said (yours was worded respectfully and at least offered CONSTRUCTIVE advice rather than the pile of "BAD JOBB DUDE" ones which added nothing to the discussion. What I'm saying is, if yours was the only "negative" opinion I wouldn't have said anything, because it was respectful (as you say) and a counter-point is useful. But no one needed 10 comments in a row telling the guy his bass looked like crap. And, in reality, while it's a little over-done, it's a LOT better than ones I've seen by people who claim to do it "professionally" and on-stage, under lights it'll look pretty awesome.
