Making Generation whistles tunable…
I heard that you can make a Generation whistle tunable by dipping it in hot water. Can someone give me precise instructions and pros and cons of doing this?
Once you do this, how hard is it to tune? Do you just tune to A and assume the other notes will fall reasonably into place?
Any reason not to do this? My 10 year old plays whistle (his is a Generation) and it would be great for him to be able to tune it.
