Thanks for the info Will! I thought that might be the case; both these guys were animals yet the sound seemed very warm overall.FloydZKing said:Yes Steve, Zickos put those heads top and bottom on all their toms and basses. Seems like part of the design as the SuperSonics in particular had absurdly raggedy bearing edges. Seems like their thought with both these and the acrylics was to generate a ton of sound and then prune it back via the heads. But put Ambos on the SS drums and dogs will cover their ears and howl. No problem on the acrylics though, which had fine edges.
