This is another one of my old tutorials on how to convert an acoustic drum into electronic with little to no modifications.
I also show a method to create your own mesh heads if you don't have the $$ to buy the factory ones. of course this is a temporary solution until you do. The idea is to get you playing and when the $$ comes you can upgrade components as you go.
