Losing tuning
I've got a newish Mandolin. I've been playing badly for a while, mostly strumming and chopping, not really doing any decent lead - that's a different issue, though.
No, the issue I'm having is that the G string (deepest in GDAE) pair seems to be in tune when open, but out when held on any fret.
I never had this issue with my old mandolin, just this one.
Now, it may well be technique. I've not a good guitarist, I have only been playing a few years. I imagine I have bad habits. Maybe the strings are a bit less tight, so I can bend them more, but I don't think it can be that obvious.
The frets look ok, not skelly, not dented, string is on the flat, not the slope.
Any ideas what I can do to remedy this?
