Re: 18" kick batter head
Before you go buy a new head, try a couple things with the SKIII first...
Crank that head. Tighter than you would normally. Those heads can sing at higher tensions. Or as a last resort, take off the muffling ring. You will be left with basically a normal coated head with dot.
Or go with the Force recommendation. But I think tightening up that head will help a lot.
