It is Nomex, my latest design. The sound is more natural, but with all the benefits of DT, very powerful, even, responsive.
This is an exemple of the sound of my DT. Spruce (wood no Nomex)/Indian RW
Cedar DT (Nomex) is just a bit darker but with the same clarity and separation.
The scratch is not deep at all, and is realy hard to see it. A repair it will make it more visible. I don’t try to fix it since I moved from my home and my shop is not set up yet. Still looking in boxes for my tools, etc, etc...
