Ho ho ho ! I just got an early Christmas present - a Bb Generation whistled tweaked by Jerry Freeman - long live the mouse!
To much of my wife’s dismay - I decided last night to play as many tunes as possible on my new whistle well into the night.
What a beatiful sounding whistle. Haunting for airs - lively for jigs and responsive for reels!
If you don’t have a Bb whistle for Jerry - just don’t sit there reading - get one !

Well, I did and I also got the “A” whistle both are very good sounding and playing whistles. I really like Jerry’s whistles.

Who doesn’t? 
Me too… I got a Mellow Dog C/D set for Christmas and it sounds gorgeous. 
At least, the D one sounds gorgeous. I don’t sound so gorgeous playing the C whistle yet. It is my first whistle that isn’t a high D, and I am surprised how even that slight difference in reach is throwing me off. My lower hand ring finger doesn’t want to land on that last hole properly. Need more practice…
Good thing I didn’t give in to the temptation to go straight for a low/alto F instead… 
I love the way those sound but I think I may need to work my way down gradually. sounds like Mr. Freeman’s B flat and A whistles would be the perfect way to work my way down while acquiring some beautiful sounding whistles…
