Ok I'm probably going to end up getting a custom bass this summer but I don't know what kind of pickups I want. I'll probably be getting the bartolini 18volt preamp in the bass, but nothing is set in stone. What I'm looking for is versatility. I want to be able to get anything from a big fat j-bass tone to a modern grand piano type of tone. Right now the combination of a Musicman style humbucker in the bridge position along with a jazz type pup in the neck position is very interesting to me. If anyone has experience with this configuration or suggests any other configuration please post.
