[Harp-L] Who manufactures harmonicas in the USA ?

[Ronnie Schreiber]

I think the Kratt company was the last domestic manufacturer to make 
harmonicas fully in-house. They still make pitch pipes (which are 
essentially purpose-built harmonicas) so assuming that they still make 
their own reeds, they could theoretically make harmonicas but they 
choose not to do so.

It's not impossible to start a harmonica company. Yonberg uses custom 
stainless steel reeds they either make in-house or have made by a vendor.
