I can't find any info on how to do this. All the set-up manuals on the 'net I can find assume you have a neck-thru guitar. Are there any good resources that show someone how to do this? My Fender American Standard P-bass has an A string that sounds awful right now...very clangy sounding. It goes away if I press down on the string above the nut, so I assume it needs to get setup again. The E string is also a little dull sounding. The strings are pretty much brand new, so I know that is not the issue. Any help or resources someone can point me to would be appreciated. Or is this something I should leave to a pro?
