Mark plays a Cloud Nine 17/16/8 dulcimer.
"My 17/16/8 dulcimer from Cloud Nine has a terrific balance from top to bottom. Featuring a floating sound board, it has a powerful presence that can really bark when I want it to; yet is equally adept at expressive lullabies. Its smart layout of chromatics make even 'The Flight of the Bumble Bee' a cinch! This dulcimer is featured on my WAY Over the Waterfall CD."
