I just channel surfed past Emeril Live, and Doc Gibbs was playing a really cool instrument that I haven't seen before. It looked like a small hand held timbale - it was made of steel with a drum head on it. Unlike a timbale the diameter of the thing was probably about 8 inches. He held it in his right hand, also using that hand to press the skin of the drum(?) to change the pitch of the instrument, and he had his other hand inside the thing - that was the hand that actually made the sound. As he moved that hand back and forth inside this thing it made a high pitched sound.... the rythym was similar to a dj scratch. The sound was sort of a high pitched squeak like you were polishing something too hard. Totally cool..... Can anybody tell me what the heck that thing is called??
