You might get better results w/ a different pickup too. Please realize that's just a very broad generalization.
Here is a spot where you can listen to some different p/u's and compare them (in one context). And recognize too that the sound you end up getting can vary a great deal depending to a large extent on your bass, your technique, and your amp.
If you spend more time looking around this forum, you'll probably see pretty quickly that the Fishman Full Circle seems to deliver much better results for most folks than the older BP-100 model.
Good luck, and happy plucking.
