Mellow Dog
Wide-body whistle, bigger sound, takes more push at the top of the upper register. For some who like to lean into a whistle, this is desirable (e.g., Cillian Vallely, who praises the fact that you can play a Mellow Dog more dynamically than with most whistles ). For others, who may prefer a whistle that takes more subtle breath (e.g., Kathleen Conneely), the Blackbirds, Bluebirds and tweaked Generations may be more suited. Most people are comfortable with all of my whistles and easily switch back and forth among them.
NOTE: Keegan’s recording is a better example of what my current Mellow Dogs sound like than Kevin’s. When I sent that whistle to Kevin I was getting a somewhat huskier sound. The Mellow Dogs I’m shipping now are closer to the one Keegan plays.

D Bluebird
Bluebirds are tweaked with the same specifications as Blackbirds. Based on a Generation whistlehead, they retain some of the Generation character in a whistle that’s voiced significantly purer/sweeter, as you can hear.

In honor of Iarla McMahon, age 10, from County Down, winning the 2014 All Ireland under 12 whistle championship playing a Freeman tweaked Bluebird, L.E. McCullough, 1976 All Ireland Champion in new dance tunes composition, composed this double jig: “Freeman’s Tweaked Bluebird,” which he plays on his own Freeman tweaked Bluebird.

Eb Bluebird
I don’t have a sample of an Eb Bluebird. The D Bluebird sample is representative, though.

Tin Whistle Comparison: Off-the-shelf key of D Generation vs. Freeman Tweaked
https://www.youtube.com/watch?v=KcaSxBkXqPg
I don’t have samples of an Eb tweaked Generation. The Ds in the videos above are representative, however. You can clearly hear the difference in voicing between my tweaked D and the off-the-shelf Generation, and Sean mentions it when he says the off-the-shelf Generation sounds “raspier.”
I’ve voiced my tweaked Generations based on the classic, pre-1980s voicing, which was noticeably purer, more birdlike than current Generations. The video features a bluetop nickel whistle. The difference in sound compared to a redtop brass tweaked Generation will be too subtle to tell from a recording. I would consider that example to be reliable for either brass or nickel tweaked D/Eb Generations.
