Accordion reeds drifting out of tune
A couple of the reeds on my box recently drifted slightly out of tune. It’s a two reed unit, and a couple of notes have become ‘wetter’ than they were. I have played it a fair amount since (it seemed to happen over a period of a month or so when I didn’t play it at all, possibly after someone spilled a pint of Guinness on the case I keep it in) and most of them have come right again, I think.
One note still sounds too wet, though. I’ve had the box apart and can’t see any obvious problem. I’m loath to go poking around as I note the individual scratches on the backs of the reeds that the original tuner made. I’m guessing that a single scratch would be enough to change the pitch of a reed by a cent or two.
It’s not a problem when playing jigs and reels, but I accompany a couple of singers, and holding that note produces a warble I’m not too fond of, and which doesn’t match other sustained notes.
Can anyone shed any light, or give any (helpful) suggestions?
