Bob with his Cocobola 12-string SuperSlide.

Dr. Bob: “This ranks with the finest musical instruments I’ve ever seen or touched. I am truly spellbound.  The form, sound and ergonomics are superlative. . . As a musically inclined surgeon of 32 years’ experience on either side of the skin, I thought I had seen and heard it all - not true - the SuperSlide is magical.”
