So... I have an important gig tomorrow and my concertina has decided to play up and I'm not sure how to fix it.
Normally, I would be able to do these things myself but I can't figure out the problem and my copy of David Elliott's book has conveniently disappeared...
The problem is that when you play the G# on the push, and then stop pressing the key, it still sounds quietly until you change the direction of the bellows.
My main questions are:
1) What is wrong?
2) Is it fixable by my?
3) How do I fix it?!
It would be great if someone could get back to me ASAP!
