Has anyone done a sticky tack/poster putty tweak on a Tony Dixon Trad?
If so, what difference did it make in the sound? Any change in the high D or the low D?
dont think the Dixon trad need tweeking

I think you are right.
I can not, however, leave things alone.
I filled the area under the windway with bees wax and created a smooth wall.
I found it actually better stabilized it overall, especially at the low end where these things are rather easy to over blow.
It did seem to take a wee tad out of the complexity in tone from a rather pure sounding whistle to begin with.
“Seem to” being the key phrase here. I don’t think its any real issue.
This is all very unscientific mind you so… YMMV.
I tried it, too, but I couldn’t hear any noticeable change.
I too had thought about trying to fill the area under the windway on the dixons. (It’s fun to experiment) It looked like it might be a bit hard to get at that area way down there, those fipples are long…
Ditto the above. I tried it, and found it made little difference. As Aanvil says, a bit more stable, but a bit less complex. I decided I prefer it untweaked. But no harm either way.
I use the blunt end of a 3/16" x 12" bamboo meat skewer to tamp putty into whistle cavities. Works well.
Thanks for the input. Now I have to decide if I am willing to sacrifice some complexity for a little bit of stability. (The stability of the low D was what I was hoping to improve. Aanvil and MTGuru say that it would…)
I´ve tired it too. The improvement was very slight. If you do this tweak with a Feadog or a Generation the improvement is more dramatic.
Wow, I don’t think I have ever seen so much agreement on a tweaking question.
In my case, my Trad seemed a little easier to play, but it lost too much of the raspy complex sound that I wanted. I already have sweet, pure sounding whistles that I like better. It also seemed to take some of the fullness of the bell note away.
If it was my only whistle, I might have left the putty in place. If you don’t pack the putty in hard like I did, it shouldn’t be hard to remove if you want to experiment. (I like to use the blunt end of a chopstick to position the putty.)
