I put Studio X heads on the batter side of all my Tama toms about three months ago and they really sound great. I was thinking about putting the same on my resso side, but I'd like to do just one and hear what I have at that point. If it sounds good, I'll do the others. In the mean time I still have the Tama stock heads on. I did the same thing with the snare, but as yet I haven't gone after my BD. I'm going to try something similar with the BD, but I'm thinking about trying one of the new Evans heads to muffle it. I'd like to leave the Tama stock head on the resso side for the logo. I'll see what happens in the next couple of weeks, I'm talking to my wife about the tax refund.
