I have (as other TBers) a new set of Elixer strings on my bass for the free trial, and I noticed when I was at the recording studio that when I listen critically through the headphones (as opposed to on stage) I hear a choruslike over-tone on my B, E and some Astring notes which get more pronounced as I go higher on the neck. I just spent an hour trying to adjust my intonation and even pickup height and I can't get rid of it or get my B or E strings to intonate properly. I am strung through the body, should I just go through the bridge on my lower strings? When I try to adjust the intonation on the B string the breakangle across the bridge is very steep where it comes out of the body. Any suggestions??
