These ones are great!!!
The offer significant control of sound and dampening, without have to use tape! I always disliked tape usage, because even though it is efficient, it looks kind of weird.
These solve your problems, because not only they look great, but they are also offering much more control than tape.
By adjusting the amount of gel pads you put, as well as their size you can hear difference in they sound quality.
I use them on a Catalina club jazz, in both toms and snare drum and they really make my sound better. I have to admit that they have less impact on a snare drum (a tape can actually achieve higher dampening) than on toms.
