FYI I spelled “tweaked” both ways for future searches.
Anyway, who has, or has played both of these and can compare them?
I should be able to successfully mash the top of the windway myself, but can’t cut/shape the mouthpiece. It looks like these are the two main things different about the tweaked version.
If I can mash the windway myself, is it worth the extra $15 to get the tweaked version?
It is going to depend if you mash it evan, and then raise or lower the blade to split the air stream. I have both mashed and un mashed. If you mash it yourself find something to use as a spacer such as a feeler gauge to stop the mashing where you want it.
I haven’t played a pro tweaked Clarke. I tweaked a few myself though. It’s very easy. You can both “mash” the windway and adjust the fipple blade yourself. And you can keep doing it until you’re happy with it. I haven’t yet bought a pro tweaked whistle. I’m not saying I never will, but up until now it has felt really redundant. I can tweak cheapies myself, so when I buy a whistle for more than $8 or so, it’s usually hand made.
