It’s a Thumper Custom Drums Keller maple shelled nesting kit. 20x20 bass drum, 15x11 floor tom, 10x6 rack tom. Been gigging them for over 20 years. Have a 12x6 that goes with the kit, and the 15” floor tom is split as well, so if I feel like a 5 piece, I can do 10/12/15 and still only have one case. Was great for back in the day gigging out of a Van with the band. Takes up a lot less space.Looks nice; specs on the kit, please.
