I have a Dean Razor j-bass with active pickups. What strings should I use to get a warm, smooth, and punchy tone, perhaps something similar to 70's reggae or soul music. I know my bass is not a good starting point, but what kind of strings would steer me in the right direction? Thick flatwounds? The bass is rather trebly and hissy, which is annoying, and I often find myself rolling down the highs. Any help? Thanks!
