Anyone have any opinions on the Burke brass low G? Thinking of putting it on my christmas list.

I have a Burke low G aluminum and it’s fantastic. If I had to do it over again, I would go for brass; I don’t think he was offering them in brass when I got mine, just composite and aluminum. I had a composite low G first, but found its tone rather weak. The aluminum one sounds much better and I’m glad I switched. I would prefer brass if I were buying one today, because I like the heft of brass and the way it tarnishes over time; I don’t like shiny instruments I guess
But if you’re not wedded to low G, I would recommend going for an F instead. There’s something magic about a low F whistle, a certain indefinable quality that none of the other low whistles have.
michael burke is making over 60 different whistles, but he doesn’t make any low G’s in brass:

i have a composite low G, light as a feather to play!!
I have a low G AlPro which I love. I also have an Overton and a Copeland low G and all three are superb instruments, each after it’s own fashion. The Burke is like no other low whistle I own; very pure and very easy to coax a singing, wailing tone from. It has a plasticity of tone and intonation that I really like. I love dueting on it with a raspier or flutier low whistle, say a Copeland low D.
Like Brad I’m also fond of low Fs. Here, though, I think that Grinters are special: that’s the low F I enjoy playing most. I also very much like my Olwell F flute, come to think of it.
I am borrowing a few low whistles that I can comment on:
Howard low D
Dixon low D
Dixon low F
Burke G AL Pro
Susato A
I also own a Jubilee low D AL S4 which I’m waiting on a new tube with offset holes.
By far, the Burke is the most enjoyable to play, and I like the sound. It’s sound is more pure, clearer sounding, but to me, the fact that it is easier for me to get consistent sound out of it, puts it at the top. The Howard and Dixons are close in sound quality, but the price of the Dixons would push me in their direction, especially since you might be able to get two low whistles for your budget (do you have a budget in mind?), especially if you find someone to buy used. Nothing special about the Susato. I prefer Dixons over Susato myself, but that may just be my playing style (breathing technique, etc).
I love mine. Let me know if you’d like to hear a clip and I’ll send you a link.

The copeland low G is stellar.
I know I would love to hear a clip, if you would post one.

I really like the Burke low-G. I played one in Song of the Sea a few years ago and was blown away by it. Funny, though, when I finally got one, it wasn’t that different, sound-wise, from the Water Weasel. It’s much easier to play, though. It has that low-whistle sound, but in a very manageable and predictable package.
I play aluminum low Gs by Mack and Mike. Both are fine instruments. As with all Burke whistles, Mike’s low G exudes a kind of ‘finished’, mature design quality that I enjoy. The sound of his G is the same full, pure sound that one comes to expect from all AlPros. If you are looking for a complex sounding instrument, this is not it. If you are looking for a dependable, pure sounding instrument that can be fully used in the key of C as well as G, look no further…
Best.
