I have a set of
Yamaha Beech Customs. I'm not home right now to check on all that stuff, but I know I have
remo coated (not sure about the type) heads, I play with
regal tip nylon jazz sticks (real light and stand up to a pretty good beating). I already re-angled my tom, thinking maybe I was hitting the rim and messing something up that way, but it still de-tunes, just not as fast. It's in my basement, so it stays in a good temp range. I think I got all the stuff, and hopefully it'll help us figure this out. Thanks guys and let me know if you think of what it could be.
