Received my Mellow dog C/D set from Jerry Freeman a few days ago.
What can i say? These whistles tick all the boxes, responsive, sweet in tone, and easy players. I love these two whistles, i can really get a lot out of them without trying too hard, they sort of play themselves. 
Thank you Jerry, great job!! 
Do you tweak other keys? Bb perhaps? If so I’m interested.
It’s a shame feadog or gens don’t make whistles lower than Bb ( a low F mellow dog would be fantastic. )

I’m with you Chris. As a new player I’ve found them easy to adjust to.

Hear, hear! 
Just wanted to chime in that I received my Freeman Blackbird from the whistleshop last week and I couldn’t be happier with it. Thank you again Jerry.

Hey, Jerry, do you make the C body available separately, for those of us who already have a D?
Sure.
It’s $5.00 plus $4.95 postage.
Best wishes,
Jerry
Hi Jerry,
While we’re on the tweaking topic, can you give us a list of all the whistles you tweak?
Thanks Chris
Hi, Chris.
Sure. And btw, the tweaked Generations have improved over time, and I’ve been able to lower the price as well.
