In the past I have purposely skinned dunun with different thickness skins on either side. Specifically a very thick one, and a much thinner one on opposite ends of the same dunun. The I use the mail weave closer to the thin skinned side. This gives me two distinct tones on each dunun, six tones to mix and match at will on a set of three dunun. I found this to be nice, especially when playing with other dunun players. I have alot of choices on which side blends tonaly with the other instruments.
Perhaps this is bad, in that they are not equal and identical. But for my ears, it has worked pretty well as a method. Does anyone think this is a bad idea? (I ask now, because I just finished the wood on 7 new dunun. I figure best to get any feedback prior to repeating my old process described above.)
