Buddy Rich used several manufacturers throughout his career including Ludwig, Rogers, Slingerland, & Vox kits. But he mostly used the white marine pearl Slingerland kit. You can own his 1968 kit that's been discounted to about $23k from Donn Bennett. (Scroll down to the 7th row.) Several other famous kits available from his 'Drum Vault'. I'm sure financing is available. π΅
