Re: Question for Bermuda
As stated in the article, they're Impact, but I also happened to have North and Staccato kits. The Impact shells don't scoop out though, as evidenced by the tom at the right, and they also have sound holes, which pre-dated both Ludwig's Coliseum snares and OCDP's large vents.
I toured and recorded with Impacts for 21 years, although only for a short time with the concert toms. The shells are thin, so they resonate well and even the concert toms had a great sound, but I preferred double-headed toms which were quite a bit richer.
The kit in the picture is gone, but I still have the Simmons pads (and the whole SDS8 kit) as well as the drums I recorded the track with.
