"Concrete Sledge ML"[]
Although he is known for Dean/Washburn signature models, he did own and use a Jackson style guitar for a while. It can be seen on a live video form Monsters of Rock in Moscow, "Primal Concrete Sledge", 1991.
Not much is known for this mysterious guitar, however later Dean issued its replica as "Concrete Sledge ML" for a limited run. Notably it featured 25.5 inch scale (Dime usually preferred 24.5) and non Jackson headstock.
