I recently purchased a 1979 Rickenbacker 4001 and although it is a great bass, I find the E string output for the bass to be unusably low. I have read a few threads online pertaining to this issue but I still have not found a practical solution. Has anyone else experienced this problem before? I have not bypassed the capacitor for the bridge pickup, so I think that might add some low end and allow the E string to sound even amongst the others. If that doesn't work, I think I might have to swap out the pickups. Any other recommendations? Also, this is the first Rickenbacker I have ever owned so maybe it sounds like it should. Are there any Rick experts living on Vancouver Island that might be able to offer some advice?
