Help reducing A String ringing
Hi, my A String seems to be ringing a lot - I this is because the notch in the fingerboard has become too deep.
I've put a piece of leather on the notch, which solves the problem. However, I'm not really convinced this is going to be good in the long-term
Are there any other 'quick fixes', or should I just get my violin checked?
Do you mean buzzing? Ringing is usually a good thing. If it is rigging as overpowering the other strings you probably need a sound post/bridge tuning. If it is buzzing that's an entirely different problem.
If it's a problem with the groove depth in the nut, DO NOT USE SUPERGLUE TO FILL THE GAP. It'll slice the your strings like a hot knife through butter (don't ask how I know). Some sort of epoxy/ ebony dust mix will work.
