I've been having trouble with getting a good sound out of the low B. When I got the bass, I was a novice player and didn't realize how bad the low B sounded. Now, with a more developed ear, I ha e turned away from the bass cause of it. I'm pretty sure I've narrowed it down to the strings since I've messed with different setups on it. Any suggestions? I've already tried EB Slinky's and D'addario XL's
