Hi WyoBadger
Have you tried re tacking the skin, or is the tear too big for that to be feasible.
I have a drum by John Jackson, with a partially cured goatskin head. It is quite hard and is the only drum I have that gets any treatment (unscented hand cream). It plays reasonably, especially in the bass, good for singing to, not so good for fast jigs and reels.
Before buying a new skin, you might be better talking to Rob Forkner, RobBBQ on the board, and see if he can supply you with the type of skin to match what you have.
Metloef Drumss1m0n's suggestion that the head might be glove material may be correct, it also could be vellum, which makes good drum heads as well.
If you are on Facebook, join the bodojo group, and ask your question there.
