Regardless of what pickup you decide on, you might consider using an FDeck preamp - it has volume control, phase reverse switch, AND a high pass filter, which many of us find very useful in dealing with some of the issues you will encounter as soon as you try to amplify your DB. It is small and light, and can easily be attached to your bass using Velcro. Or, I think you can use it with a belt clip. Just another thought as you start down the rabbit hole of amplification.
