Hi everyone, this is my first post on this forum... I already tried to search the posts on unbalanced string response issue, but couldn't find any specific suggestions.... Anyway, here is my problem: I own Yamaha BBN4 III bass (the one with passive soupbars). I run it through Tech 21 SansAmp and sometimes through some cheap racks (Behringer Ultrafex pro, and Alto parametric EQ). Whether I'm going "straight" to amp (I don't have my own, instead I'm renting some Carvin or Randall) or through pre-amp or racks, my E string tends to go louder and bassier than other strings. I already tried different string sets, but currently I'm using Fender Pure Nickel. It seams that whatever I do, the problem persists. I've only noticed that when the strings are fresh new (about few days), seems like the problem is not that noticeable. Could it be cause of the pickups? I'm planning to put EMG 35DC and 35P, or some Bartolini if I get lucky enough to find a store that would send 'em to me here in Serbia and Monte Negro .
