I've seen the buzz come back after lowering the tension and bringing it back back up to tension. The buzz goes away for a while. But it comes back eventually. You don't get the wild pitch changes we do here, so you hopefully won't have the buzz come back. But then again a 5 cent pitch change was able to bring the buzz back. The only way I could stop the buzz was to refurbish the agraffes. The techs at the store should stand behind their work, so you should be covered. Right? Tim Coates
