Tone: Very slightly reedy, with a complex chiff. Also, the sound wasn't as harsh as some loud aluminum soprano whistles. It's definitely a bit sweeter, though the tone is still quite strong.
Volume: Above average, but with a wide variance (though this does change the pitch), and increasing dramatically in the 2nd octave, especially in the top end. By way of comparison, when played in tune, the first octave was slightly louder than my Meg, and the second octave was quite a bit louder than the Meg's. In some ways, this reminds me of a Susato.
Responsiveness: Plenty responsive. No issues playing ornaments at a fast clip.
Tuning: When blown with the proper breath control, this instrument is in tune when warmed up. This particular whistle is a non-tunable, and like all non-tunables, care should be take to make sure it's warmed to be fully in tune.
C-natural: OXXOOO produces a sharp C-Natural. Of course, this means that OXOOOO is very sharp. OXXXOX is just right.
Hole size and placement: The holes are well-rounded, polished and slightly chamfered. The E hole is a little larger than usual. D hole is placed a little away from the pack. Neither of these things caused me any issues. There's also a little bit of a gap between the first three and the last three holes. Since most people cover the first three holes with fingers from one hand, and the last three with fingers from another, this should in no way be an issue. I've heard of at least one player that plays with four fingers from one hand and two from the other, though...if you're one of these types, the hole spacing may take a little getting used to. But I would expect that only a couple of people on the planet play that way.
Air volume requirements: slightly lower than average. This was expected, due to the very small windway.
Air pressure requirements: Medium, with a medium amount of backpressure. This requirement goes up to high in the 2nd octave, and if you're a little shy or treat this instrument gently up there, it will reward you by falling out of the octave and honking at you. You have to keep the pressure on and your breath precise with this whistle. I found that if I played my Meg after playing this whistle, I tended to overblow the Meg, until I readjusted to the Meg's pressure requirements. Neither of the D's are particularly easy to control. The first octave D is a little weak, and takes a less breath than the notes above it. You also have to be careful hitting the second octave D quite precisely if you're using XXXXXX. If your breath control is off, this whistle has a tendency to honk that note.
Clogging: When played cold, started clogging right away. The Overton website is up front about this whistle really needing to be warmed up before playing to help with moisture control. When warmed, didn't start to clog until 25 minutes or so, so pretty average. The whistle didn't cut out when wet, but the second octave did become pretty unruly, becoming harder to hit without honking. Like most aluminum whistles, if air conditioning vents onto it directly, it does a good job of going cold and then getting cloggy. I would recommend giving this whistle the Duponol treatment.
Wind Resistance: Poor. I usually initially judge wind resistance by seeing how the whistle handles the 1-tune 30-foot walk from the parking lot when I stop by the supermarket after work, and while pumping gas at any random gas station that I happen to be at when I have the whistle with me. I figure these are good ways to get a non-contrived setting for wind testing. A breeze cut this one out on me during the parking lot walk before I had gotten 3 notes out. I was hoping that with the added backpressure, this might have made a good outdoor whistle but it was not to be.
