"Exactly ;) Although I usually do it just like in this pic, it's ok of it's stuck on the soundboard too, you just don't want that contact to be intermittent, that's when you'll get the nasty click-buzz just like tapping the…"

"I want to try it, when you look at the picture of the Phyrgian Kid you see he didn´t put his pickup under the strings. It must react on the vibrations of the lid of the tin can. Which means it should also work with nylon strings. But best way…"
