If
you possess a mouthpiece which is not listed in our table you
can provide us with it for measuring purposes. We will then produce
an appropriate reed screw for this mouthpiece and incorporate
this into our GF System programme.
We
would be pleased if you would inform us if you are using a GF
System reed screw on a mouthpiece which is not in our table.
Thank
you in advance, Your GF System Team
