Not at all MT... I've always been curious to tune whistles... One of the bands I'm in has a Bb whistle around somewhere that we only use occasionally, but I'm positive that it's a few cents low and it drives me NUTS!!

So potentially, this may only be 'fixable' with major surgery.. If the fipple is currently pushed in as far as it can go, then I might possibly have to Dremel the whistle down a hair eh... I may wanna experiment on a few cheepo Clarks or something first... LOL!!

Fortunately, all we use are the 10 dollar, red and blue and green plastic fipple ones... Pretty much disposable flutes eh...
