Re: Poltergeist on my A strings?
Do they go out of tune even before you've played them after tuning & do they go 'sharp' or 'flat' ??. I tune up (or at least check the tuning) on my mandolin before i play it,& very often the "A" strings will go out of tune to 'a degree' after i've played it for a while. If the strings are simply going out of tune on their own - then it's odd to say the least. With no problems of humidity here in the UK,i can tune a mandolin,put it in it's case,come back to it several days later & it'll still be in tune.
As you mention - it might be the nut slots. If the strings are binding,maybe simply getting a small piece of coarse brown paper,folding it up to make knife edge,& polishing the slots a bit to smooth then out might work,or apply a tiny amount of some form of lubricant.
I had a problem with one of the "A" strings on my Weber going 'sharp' ?. I couldn't understand that at all until a Cafe member explained it to me. I used a piece of brown paper,gave the offending nut slot a good polishing & it's been fine,
