Just another thought. I have noticed that some of the MG calls that I received have a 1/4" or more of the wedge exposed. This has never worked for me and I had a tough time tuning a MG like this. I have taken the wedge and sanded the flat part so that the wedge sits further into the insert. This really helps unless you have a thin shaved reed. Go slow with the sanding...a little goes a long way. Gettin' thirsty, think I'll have a cold one. Murph.
