Currently, my Jazz bass has D'Addario nickel round wounds in "light" gauge. (0.045-.100) The feel is good, but I wonder if a change is worth it. My gauge of strings on my electric has crept up (I'm now using Ernie Ball Power Slinkies (0.011-0.048) on my Les Paul. On acoustics, I try to stick with what the manufacturer puts on it. Bass... Does string gauge make as much difference in the sound as it does with guitar? My bass has EMG-JX pickups. I'm looking for a fatter sound. (Yes, I know that it'll still be a jazz bass no matter what. ) I know a lot of basses come with 0.050-0.105s, and my local dealer has some Ernie Ball Power slinkies with the E string at 0.110. I'm also thinking about a bone nut and a high-mass bridge. So, what would you do if you were contemplating changing something for a better sound?
