I have a Paul McCartney model Rickenbacker at my disposal to use whenever I want. Its a nice bass, classic sound and all that but I can't bring myself to use it. The problem with it is that there is an imbalance in string volume that I cant seem to cure and it makes the bass nearly unusable IMO. If I set my amp volume such that I can hear the E and A strings, then the D string will clip out my preamp in a big way. If I adjust the volume such that the D string is not too loud, the E and A strings have very low volume, sound thin, and get buried easily. The G string is ok. I have adjusted the pickup height with slight improvement but thats not going to be a fix even at an extreme setting. The string heights are all perfect and even as well. Beyond that, is there any fix for this problem? Anyone else have it happen to them? Its a nice bass and I would like to play it but I simply dont want to with the problem it has.
