Emax

I used a razor to cut through the traces. There were a couple of traces very hard to get to because they are so close to other traces that do not require a cut.

I probably need to go back a do a re-cut on each trace. I will used a Stanley box cutter (razor) and make better cut. 

I don't understand the question about about buzzing the mods out afterwards. Can you elaborate?
