Chromatic Harmonica Tombo Deluxe UNICA Formal 1844 ※※About the product※※ This is a Tombo chromatic harmonica, the TOMBO Deluxe UNICA Formal 1844. Chromatic harmonicas are also called slide harmonicas. By pressing the lever on the right, you can produce a sound a half-step higher, so you can play songs in any key with just this one harmonica. Unlike regular harmonicas, you don't need to prepare many harmonicas for major keys, minor keys, or different keys. The ability to play various songs without needing multiple harmonicas is a key feature. It has been many years since I purchased it, but it has mostly been stored away in a drawer. I recommend this to anyone who wants to try a chromatic harmonica. The mouthpiece will be sterilized with alcohol before shipping. Thank you for looking. #Harmonica #SlideHarmonica #ChromaticHarmonica #TOMBO #UNICA #TomboHarmonica #ShowaRetro #Metallic
