I just bought A200CE #470 and it has ringing overtones that simply overpower the sound of the strings at some fret locations. It is so bad that family members upstairs came downstairs to ask what that high pitched screetch was accompanying some notes - "Is that your guitar? How is it doing that?" It really is quite offputting - high harmonics coming off not only high E and B but some of the bass strings - A string 5th fret is especially bad.
So the question is can this be solved by changing the material in the saddle and/or nut? Is it a string issue? The guitar has D'Darrio light phosphur bronze strings on it. Something else?
