Does anyone know of other whistles that sound like a Clarke? It has a sort of breathy sweetness that I really enjoy. So, just wondering if other whistles exist with a similar sound. Thanks!
My one disappointment with these is the shear ammount of air
they require 
a tad loud too.
Jerry Freeman tweaks some keys of Shaws, which helps with the air requirement.

I might look into getting one of these and asking Jerry to work his magic on it. I’m just looking for something with a pure and sweet sound with a little breathiness. If anyone else has suggestions, I’d be glad to hear them.
Here is the Wandering Whistlers review page;

Look under the ‘Inexpensive’ header for the Tweaked Shaw.
Summary
If you like Shaws or Clarkes with that traditional chiffy sound, Jerry’s tweaked Shaw is a definite improvement over an untweaked version. The more I play this whistle, the more I’m reminded of my roots (I started on a Clarke) and the more it grows on me. Plus, I can see that I’m just going to have to have it for outdoors play and loud sessions.
Does Freeman still do Tweaked Shaws?
I don’t see them listed on his Ebay page.
