I only tried the first bass I bought because that was in a shop. I've bought "unseen" ever since, because I haven't got a choice. There's damn all interesting up here in 'doom and I don't see that changing any time soon. The two music shops try to be all things to all people, and by all people the pecking order is guitarists, keyboard players, drummers, bassists. There's one bass for every four guitars.
I buy them, I keep them if I like them and I sell them on if I don't. I always buy second hand as that minimises the losses.
