I am looking for the best pickup that can be easily removed from the bass and put back on. I am going to use it on a bass that will be used for both jazz and classical music. On my other bass, I have the full circle, which is pretty good, but I want something that I can easily take off the bass for this instrument (so I don't have to have it one when playing classical stuff). I have an Underwood, but I am looking for something with a more natural sound. Any suggestions?
