Fine. Its in the creation of a new electronic drum (don't hiss and spit, I learnt drums because there aren't enough drummers around UK)...
Basically I'm replacing the strings with a mesh, which becomes the drum head. The pickup goes below the mesh, and acts as a piezo, like roland V drums. Another way would be to thread pieces of metal through a normal drum mesh head, so as not to diffuse the magnetic field as psw implied. I find the best way of testing is good old practical testing.
My idea is to eliminate the need for midi- I have a few old pickups lying around and plenty of spare parts to create such a device, except the mesh, which I would need to manufacture into a skin with hoop.
I'll then plug the drum into my Line6 spider amp, and tweak it till it sounds somewhat right. If it works it could be the era of a new electronic drum, if not, meh, I'll keep it as a memento.
Thats the idea anyway! If I see it pop up soon I'll know you stole it, but I'm sure it won't be that great anyway, but I'm curious.
