I’ve had to think really hard on this because I don’t want to offend, mislead, or misrepresent…
Let me first say that I have played only this one whistle, so what I have to say is based entirely on that.
I bought a non-tunable whistle with a silver fipple cap for $65.00 + shipping.
I’ll start with what folks might consider to be the bad: The finish work is not as nice in the hand as it appears in the picture. The joint between the silver cap and the wood body isn’t very clean. The bore is slightly off-center from the bell end to the mouthpiece. The fipple plug is grey plastic - looks to be PVC, and was glued (but seems to have shifted slightly in transit, but I was able move it with a little effort to realign it with the rest of the relief cut on the beak when it arrived. I had no reason to believe it would move again, based on the good fit in the tube). The relief cut is a little shallow (IMO), leaving the mouthpiece a little thicker than what I am used to on other whistles, and isn’t very smooth.
It shares a basic design similar the O’Brien and Tommy Dion whistles, and sounds very similar as well, although the upper octave is a bit more breathy, and the lower octave tends toward a softer, purer tone, and it can’t be pushed like either of them. The bell note is not as strong as it could be - a bit softer than the rest of the scale. It has slight back pressure, and some chiff. It has a nice feel in the hands, and I like the spacing of the toneholes. It also has nice action. The ramp was well cut. The intonation is adequate - neither great, nor bad. It takes a little more breath control than either the O’Brien or the Dion - in fact, I think the OP probably would be satisfied with the whistle I recieved.
In all, I would stress that this is a very fair whistle for the price. However, people shouldn’t let others who have no experience with these whistles influence their expectations. I think Tyrone is in a position to build himself a reputation as a good whistle maker, if he chooses to. He certainly has a good understanding of what he is doing, and with some refinements of his methods, techniques, and his overall finish, these whistles could be worth considerably more money than he is asking for them. As they are, I would recommend them for the price.
This is how the whistle was when I first received it. I have since removed the plastic fipple plug and replaced it with black delrin. I gave the new plug a little bevel and advanced it in the tube slightly (toward the ramp) and this has improved the difference in tone between the lower and upper octaves, making it more consistent. I pinned the plug in place with a 1/16" brass pin, and slimmed the mouthpiece more to to my liking to allow for better embouchre. At this point, it could probably stand a minor re-voicing of the tube, but I am going to hold off on that, because I rather like the way it plays - I always did - otherwise I wouldn’t have bothered modifying it at all. And to be clear, what I have done with the whistle probably would not have worked if the basic “mechanics” of it hadn’t been good to start with.
