I've always absolutely loved the Rickenbacker bass sound. Clear, nice high end and a really kicking low end.

Of course, I don't have a Ric, but, I do use round wound strings to get that bite. But the gear, like for guitar, is only a part of the overall sound. The gear provides the foundation from which the player adds the tone and technique to get the sound/tone they want.

One of the things I like to do that sounds counterintuitive is to cut the bass below 100hz and to avoid having other things in that frequency range competing with the bass.

Like everything else about this thing we call recording, I'm still learning and experimenting to try to get it right.
