I think
clink said it best above. Too funny.
It just varies an awful lot based on your bass, bridge, string choice, amp, preamp, tonal preferences, the whole package.
Anyway, in my case, I used the K&K Bass Master Pro for a long time. Now I use a Rev Solo II and I dig it. I demo'ed a Schertler DYN-B and decided not to purchase it, but some people say they get a very natural sound out of it. And on it goes.
A mic sounds better than any of these to me, but is not always workable on its own. So I blend a mic and a p/u.
Anyway, back to the OP ...Here's an
all-purpose link that might help, although if you take the time to sift through all the additional info in this forum there is much, much more information on pickups available too. The newbie link as it's called is just a starting point, and some of the threads actually might be a little dated.
Uncletoad had a great post about like the top 5 or 10 things to check if your Full Circle was not performing up to your expectations, but I can't find it now.
Like
this one is good, but it ain't the one I'm thinking of.
And
another.
And
this.
Hm ... maybe
this is it.
