Chasing a buzz

[Doug Davis]

Thanks Wayne,

I thought it might be a sympathetic buzz on the top side of the string but eliminated that (I think) as I can't affect it in any way by using 'support' fingering above the note or not....no difference - if that makes sense.

also, to the "no matter what I do"; I had the same thoughts... its starting to remind me of working on my old vw years ago. trying to get out a ''flat spot" in the carb...after a half dozen corrections had no effect, I figured out it was something else completely different. But there are aurguably less variables on an upright! but still I did wonder if maybe it was a flat spot in the string or something....but nothings visible? maybe inside the core?
