An hour ago, I've finished to "improve" my drum kit.
Firstly, I've begun with the snare drum. It was a part of my drum kit which I didn't like anyway. I've tuned it tightening the two drumheads. Later I've tuned the snares and finally I've added a piece of cloth to reduce the sustain.
The next instrument had been the toms. I've tuned the first one, but I've liked how sounded the others.
I'm very happy with the result of the snare drum. I think that my drum kit is ready to receive the new cymbals.
