Someone is gonna crucify me for saying this, but here goes. His snare in the video sounds like wood for sure. Since yours is metal it will tend to be ringier than what you want, so you need to deaden your head. Duct tape (cringe), those o-ring things, hell even maybe a Pinstripe head. It can be done, but you will have to think outside of the box on this. You will still need to keep the head pretty tight so it doesn't sound mushy like a wet cardboard box. I just don't think a coated Ambassador is gonna get you where you want to be.
Ok batter head is gonna be pinstripe , for bottom head ambassador or diplomat?
