The Clarke Tinwhistle Company was started in 1843 by Robert Clarke. The traditional Clarke whistle you can buy made of rolled tinplate with a wood block fipple is made in essentially the same way as the originals in 1843. The Clarke Sweetone is a more modern verson of the Clarke whistle, using the same basic body construction of rolled and sealed tinplate, but with a modern, plastic mouthpiece designed by Michael Copeland (of Copeland Whistles). It made it's appearance in 1996, and I got one right away. To tell you the truth, the Sweetone was the biggest factor in my continued whistle practice at the time. I was a little frustrated with the Clarke original I had. It took a lot of air, and I was still a cigarette smoker back then. So, I got a Shaw (big mistake!) because there wasn't any resources to tell me that Shaws took even more air than Clarkes! When I finally got a Sweetone, I was in heaven!
The Meg, introduced in 2002, is a lower-cost version of the Sweetone--the same molds and construction methods are used, but the Clarke company takes advantage of cheaper labor and materials overseas to produce a cheaper instrument. I've read reports of inconsistency among them, but since these came out, I've owned and given away perhaps a half-dozen of them, gotten in various ways (bought from different stores, gotten as part of trades, etc) and all of those have been consistent in make and quality.
For that reason, I am not going wax poetic talking about the playing characteristics of this whistle. For all intents and purposes, if you know a Sweetone or read my Sweetone review, you know this whistle. I've never gotten an iffy one, but have read one or two stories about people who have, so take that for what it's worth.
Volume: Low side of medium, same as a Sweetone.
Responsiveness: Moderate, same as a Sweetone. The tone of this instrument keeps my fastest ornaments from sounding crisp.
Tuning: In tune across it's entire range, same as a Sweetone.
C-natural: OXXOOO produces an in-tune c-natural.
Hole size and placement: This whistle has holes are average size and placement.
Air volume requirements: Low side of medium.
Air pressure requirements: medum low. Like the sweetone, this is a very easy player both in terms of breath pressure and air needed. It doesn't take much effort, even at the top of it's range.
Clogging: About the same as a Sweetone: Starts clogging in about 20 minutes. Duponol helps.
Wind Resistance: Medium. Good breezes knock this out, and I have to do the wind dance (where you shuffle around while playing to try to keep the wind at your back) more than I'd like, but still, I've been able to play this outside with some success.
