I just put in some QPs and I find when I play below the 8th fret I can hear what sounds like fret buzz or possibly distortion. I know the strings are not the issue as they are quite high at the moment. So I lowered the pickups to half the height they were at. It helped quite a bit but not completely. Do I have to lower the pickup so they are flush do the pickguard? They're not too far from that now. It seems wierd to have more powerful pickups but not be able to harness their power because the signal may be too strong. All the sound issues clear up when I turn down the vol. pot on the bass. The only other possible cause of this is my headphones. I use a reasonably high quality set of panasonic earbuds. Maybe they cant handle the volume? Not sure but I would think they would distort with lower/bassier notes not the notes higher on the neck. Then again, the notes higher on the neck tend to have greater volume "spikes" so that could be a part of the problem. I cant really play my rig in my house b/c I live in a condo so I use headphones. When I have my next band practice I will crank her up and see what happens. anyways any ideas?
