Well I finally tried the blue tack tweak on my Gen D’s. What a difference! After I figured out that the tack goes INSIDE the mouthpiece it was quite simple. I used white tack however as it’s all I could find. AFter agonizing for milliseconds I realized the color wouldn’t clash with my renfaire garb.
The nickel whistle squeaks a bit so I’m embarking on a blade tweak. It seems to go into the second octave a little easy.
Thanks to everyone who assisted with words of encouragement and posted their tweak secrets on the board.
