Before getting started on this mod, take out any bridge or divider between that reeds that might be there. Also, make sure that your reed block is very flat and is sealing against the current reed. This became a big problem for me when cutting new reeds. They never seemed to seal quite flat. This mod gets around that problem, which is part of why I did it in the first place. In my case, I plastidip'd the reed block to rubberize it. Depending on how long this lasts, I'm not sure if I can recommend that or not. I have 100miles on it so far though and no signs of failure...
So, ok you've prepped your reed block:
Drill a big ass hole (in the top 2/3rd's of the reed)
Cover with the thinnest reed paper. In my case, I used .25mm Yellow Polini reed paper from Treatland.tv
Step 4: Blast
EDIT: REMEMBER TO LOCKTITE YOUR REEDBLOCK SCREWS!!
