MOST EXTREME DIATONIC HARMONICA EVER - Massive New Expressive Possibilities!

Never before has so much soulful note-bending ability been packed into a 10-hole Richter harp! My one-of-a-kind prototype combines two recent inventions to vastly improve the standard diatonic harmonica (essentially unchanged since 1896), without sacrificing any of its great qualities. I sincerely hope my demo will generate sufficient interest to turn this hugely expressive new harp into a production model anyone can buy. TURBOSLIDE HARMONICA SLIPSLIDER HARMONICA
