That's really my problem too. There are SO MANY FANTASTIC instruments out there, with body styles and tone catering to every crowd. The craftsmanship is amazing too-- US, Europe, Asia, whatever.
Obviously, the "Fender Bass" started it all, and it's been around forever. And there will always be people that equates to quality, and it being the "best" choice.
I'm the kind of guy that likes to explore the alternatives. I've been looking at the P and J body styles for years, and I'm frankly tired of seeing them, and I'm tired of everyone voting for FENDER on these polls!!
This is a RANT!

So sorry, everyone's entitled to theirs. The most common thing IS NOT THE BEST. That's just me. I like DIFFERENT. Funny thing is, Spector does not really fall into this category as the days go on, haha. They're quite popular.
I digress, but one more thing: classic rock. It has the same effect on me as what we're talking about here. When I hear something on the radio from 1977, and somebody's going "I LOVE THIS SONG" or whatever, I'm thinking, "Holy crap, not again. I've been listening to this for THIRTY YEARS.
There's generations of brand new, really cool, innovative music out there, and the same goes for instrument design and manufacturing. I want to check out that new stuff.
I'm tired of looking at and hearing about the P bass. It's big and ugly and clunky.
And I'm an *******.

I respect everyone's opinions, really. But I don't have a ton of respect for someone who has not actually looked at and/or played some of these amazing new-er basses, and just picks a Fender because "that's what you pick" and then acts like it's the best thing out there.
My bad, I played an American Standard Jazz for a few months in 2001 and it had dead spots all over (new strings) and just did not feel and sound as good as every other bass I had owned (Guild Pilot, Spector NS2000B - made in China, Yamaha RBX6JM, the list goes on.)
Anyway, fire away, it's just one opinionated man's opinion. Explore outside the status quo.
