Nah, i've heard some, they really kill the drum sound. You sort of just get a toned "thump". Definetly not open. You want open, try an ambassador/diplomat or G+/G1 combo (or like i have an ambassador/G1 combo )They actually are really open-sounding. In fact, my friend and I were at Guitar Center last year, and he was looking to buy new heads. I suggested the Studio-X's, because as the name implies, it would sound like a studio. That wasn't the case, although they still sound very good.
