Hello
Kresimir---You know, I don't think very many people are seeing your question here. There are many forums at this website and it is rather confusing. You might want to post your question in the forum where people who mostly play the whistle would be sure to see it:
http://chiffboard.mati.ca/viewforum.php?f=1 <---This is the forum for tin whistle players.
It is fine to post the same question again in another place, don't worry about that. I don't know anything about your problem but I have seen people talk about bands and sound problems over there. Good luck!
