nice auction! what is the material on the back side? I see it has cracks, is it pretty stable where the cracks are? So, this actually has a piece you can manually slide to make it sound different? Sorry for all the questions, I know nothing about these as you can tell. :) thank you!
It has a couple things tracks and yes it is very stable there's not one thing wrong with this harmonica works excellent ;-) and yes it has a slider and it makes different sounds a lot of people prefer those than the ones without
