I recently purchased a student Bundy flute to learn on. At first, I thought the problem was me, but I can pluy the headjoint just fine. I suspect the main body piece is leaking. I've tried the suction test on it, and it seems to fail, but only if I use a lot of pressure. Is it me, or the flute? Is there anyway I can check? If it is leaking, what would the price be to get it into playing condition?
