Hi, I'm fairly new here, anyone help a newb?
I have a 20-button Stagi C3 anglo, D/G tuning, and I was playing it a few days ago when all of a sudden one of the keys made a squeak instead of the planned F#. It almost appears that it might be an F# one octave higher, but that's not very helpful.
I could take it apart and look at the reed, but this particular concertina it appears difficult to get apart. The ends seem whole except for pins on the side, which might be the bellow pins. Does anyone know how to get something like this apart? Does anyone know what the problem might be that all of the sudden out of the blue it changes notes on me? Any help would be welcome.
Thanks.
