There is a volume drop in my B string. All the others sound even. With the balance rolled all the way to the neck pickup it's more noticable, but with the balance rolled all the way to the bridge pickup, it's almost even w/ the other strings. I checked the string height above the neck pup, and the B is actually a tiny bit closer to the pup, then the E is. The bass is... Warmoth Gecko Bubinga Body Wenge Neck & Fingerboard Seymour Duncan Active Jazz Pickups and Tone Circuit Kahler Bridge Problem is the same regardless of amp setup. Strings are only about 3 weeks old. Any ideas what else I should check? Thanks.
