chock full of useful drum tuning info.
try different tunings and try a hole in your bass head. since everyone likes a different sound, you'll have to experiment - and the room you're playing in may be the problem, too. we used to practice in this small room with no carpet or sound board and our drummer sounded like shit, but when we moved to a better room, he sounded much better that fast.
hey, any drummers in l.a. want to jam?
