Fenders have been considered plug and play basses from almost the beginning. Whatever your preferred sound, an awful lot of players think it's relatively easy to get with a Fender and most amps. An EB-0 isn't as versatile and it doesn't work as well with some amps as others. If you like the basic tone, you can get your sound, you just may have to spend a little more time finding the right combination.
That doesn't excuse the Gibson haters out there who will bash just for the sake of bashing, but you have to admit, the EB-0 sound is never going to be considered universal.
