I've had my new concertina for about 6 days now. It's a beautiful Frank Edgley Anglo. I love the sound and everything is great except.............
Every time I pick it up and play it for about ten minutes I get a very unpleasant pain in the base of my right thumb - kind of a dull ache. I never ever had this problem with my cheap old Hohner D40 anglo. I've tried tightening/loosening my hand straps. I've tried changing the knee on which I place the concertina i.e. changing the static end. I've tried holding my hand further back/further forward.
I asked my wife to watch me play and she said she thought my right thumb looked tense compared to my left. Of course it's the right thumb that operates the air button. I've tried not using the air button unless I really have to which I know ultimately is not going to be a solution. The air button is not particularly stiff - in fact it's very responsive. The concertina doesn't seem heavy - probably about the same as my Marcus English.
To be honest I'm at a bit of a loss and feeling a bit depressed about it. I am pretty new to the anglo (5 weeks). I never, ever get pain when I play the English. I can play this for ages without any ill effects.
Can anyone out there help me?
