Jeep, if it was a black snare drum, it was probably a Gadd. IIRC, the Jordan is a lighter natural wood finish.
Definitely not a Gadd model. At first I thought the one I played had more of an off-white finish, but it may have been in the natural maple matte finish. Sorry, bad memory. The Robinson model doesn't look quite like the one I played either.
I checked Yamaha's site and didn't see a visual match under their Sig snare drums. Steve Jordon is still listed as a Yam artist, stating he uses a MSD-1315 14"x6.5" snare drum, which isn't shown in the sig or non-sig snare drums.
