I was perusing Drummerworld & clicked on Phil Ehart's- drummer for KANSAS- page & there was this picture of his set.
I thought something looked strange about the toms, looked closer & realized they're set up like tympani, with heads extending beyond the shell. I vaguely remembered seeing some drum company making something like that but can't remember. Love to hear from you Slingy experts on this one Bowing
I always liked their copper finish :)
