You can check out my Tuning page for more info on that crucial area, but I think it's safe to say that good tuning starts with good heads. I have been playing Remo Pinstripes for a long time. They're a good, basic rock or heavy jazz head, but they tend to inhibit bounce. I'm beginning to learn that the same sound can be achieved by coated heads on the toms and a proper tuning. This is where I've been heading lately.
Coated heads offer a natural muffling due to the coating, where clear heads offer no muffling.
Generally, though, I prefer a wide-open sound, particularly on the snare. I have five snare drums. However, the other four drums lend themselves to peculiarities that fit particular styles of music. It can also be used for rock when the snare sound desired is a high, ringing tonality. I purchased at a garage sale.
