Thanks for advice,
I will hack and tinker with my spare Sweetones but this may not help if as Alison says they are out of tune with themselves - which I think is the problem I specified earlier but in different words !
I will try taping up some holes.
I bought a nickel Generation with a blue top today and I'll see how that goes this evening.
Maybe no-one really cares if my whistle is 'out of tune' but it eats at my confidence and I get worried about playing at all. I really don't want to stop so I will strive to get a tuned whistle.
Should I be buying an expensive one (100 pounds or so ? ) - would that be in tune ?
