My bass used to be just fine, then all of the sudden it just started buzzing like crazy. I tried raising the action, but it was too high to be playable and still buzzed, so I took it to the local guitar tech. He adjusted the truss rod and action. When I got it, it was perfect, but it buzzed just a little too much in the lower frets. Not a big deal. I just let it go because I didn't want to mess it up. Then, ALL ON ITS OWN, the action just decided to piss me off and get higher. Now it buzzes like a beotch in the higher frets and still gets higher. When I lower it, it just buzzes even more and keeps getting higher. I'm getting ready to use this thing as firewood and get a new bass.
