I'm also a drummer. Admittedly I can drum far better than I can play a bass guitar.

Gibson purchased Slingerland, a then-dying drum company that used to be famous for jazz and rock drums (one of the Big Four drum brands) with the intent of reviving the brand. The drums they made were pretty nice (some say "the best era of Slingerland"), but their marketing was pretty abysmal: they forced every Slingerland dealer to carry Gibson guitars too! Drum-only shops thus cannot carry them, and it didn't gain much commercial success. Bummer.
Fortunately, after the last bankruptcy, Gibson sold the Slingerland brand to Drum Workshop, a company specializing in making great modern and vintage style drums, and have successfully revived the drum branch of Gretsch in the past. New models are scheduled to be released later this year.
