I’m having trouble finding a low A whistle that I really like. I’m beginning to wonder if low A whistles are somehow just the wrong size for a whistle to sound really good. What I’m looking for is pleasing tone, very good intonation and I really would like a C-natural thumbhole. Any suggestions? Or, does anyone have a whistle that meets that description that you’d like to sell?
Hi. I go back and forth between my aluminum A Chieftain and my black Burke. Both are unique in their voicing; I record with the Chieftain because it’s so distinct a sound… I play the Burke often for stuff that’s more “buttery.”
Have fun.

I have an Overton/Goldie A and it’s killer good. It clogs a bit if I don’t warm it up, but once it’s warm the sound is simply gorgeous, especially the lower register.
Funny, but most of my A whistles are part of sets - Bflat/A Abells, Bflat/A Water Weasels, and A/G Albas. They’re all fine, but my favorite is probably my Copeland.

My favourite is definitely my Bernard-made Overton. After that, both Abell and Sindt are nice whistles but not as interesting as the Overton. Even though the latter two are part of sets, they should be good enough to satisfy most players, even if they don’t quite match your ideals perfectly.
As of right now its my Burke Aluminum Low A… 
I have only one–a Hoover Whitecap 3/4" aluminum–so that’s my favorite. 
It’s one of my most well-balanced whistles. It’s moderately loud, easy to play, responsive, and has what I now think is the “traditional” sound, as it fits in quite well with the Jerry-tweaked Gen and the Humphrey Stealth.
Water Weasel. But I don’t have one of Glenn’s wooden A’s. Yet.
Of the ones I’ve played … Sindt.
