I have a Fender American Jazz Bass (Passive Four String) and a new Fender Super Bassman 300 with the 4X10 Neo Cab. I've been using DR Black Beauties for years now on my Musicman basses, but I just don't like their sound for this rig. I'm entering the studio next week and was wondering if there was a better string option available. I'm looking for a passive, old-school funk and afrobeat sound. The DR's are just sounding too boring on this bass set up...not enough punch and gut smacking funk. Any suggestions are welcome since I typically stay with the same strings for years.
