Can anybody tell me why my g string keeps going sharp,to the point that it sounds totally out of tune,but when I have it slightly flat it stays flat.
It' is probably either the nut or bridge slots pinching the string.
If, when I'm tightening or loosening my strings, I get that common "Tink Tink Tink" sound, I take it as the strings trying to hang up in the bridge and nut slots. I use the smallest mechanical pencil I can find, a .5 or .3mm I think, and put some graphite in the slots. Scraping some graphite dust off a regular #2 and filling the slots works too.
Will give it try and will post results
I think there might be some sort of laws of physics that always send the 3rd string out. That is the string that always drifts out of tune on my banjo. It is also the string that used to drift out on my Les Paul guitar, and it was renowned for doing so on those.
When I tune now I always tune all the strings just flat, then tweak up the 3rd string first prior to tuning in the other strings. That seems to keep me in tune longest.
Change your strings. My strings always won’t stay in tune when the need changing
Always raise the note to the finished tuning.
If the notch is squeking/chirping widen the notch a couple of thousandths.The StewMac slotting saws do this perfectly.
