My goal is to make a bass that's a punchy, grindy, growly beast. The searches I do for any of these keywords usually offer advice on a specific set of pickups. I'm still at the blue sky phase though, and open to any style of pickup that will meet these criteria. I'm leaning towards jazz or MM style pickups but know that a lot of the tones I've heard work, came from other style of pickups. Think: Tim Commerford's jazz tone from RATM, Flea's Wal tone off BSSM, Duff McKaegan's jazz special, Geddy or Squire's Rickenbacker tones from the 70's, Entwistle's Explorer tone in the 70's, etc. There's certainly diversity, but there's also a lot of commonality in the tones. What pickup set or combination of pickups is going to capture that aggressive, punchy, mid-filled, bark that they all seem to share? Further, what placement should I be looking for to further push that tone? Close to the bridge? Sweet spot? Both? What's the recipe for an aggressive sounding bass?
