That’s Impressive to have XB 40s in Keys of C D G and A and Its not only the substandard case…Hohner have had plenty of other problems regarding some of their Chromonica 280 c 16 hole series including myself and their poorly made Bluesband Series from China ripping off unknown Harmonica enthusiasts…While offering low price in set of various Keys…Inferior Quality Control it seems…But though I reside in Germany their after sale & service Team reacted promptly…I assume that Hohner will not reissue the XB 40 Model anymore…What went between them and Rick…I have no Idea…Brendan Power or whatever is also producing some X Bending Diatonics…But I only enjoy playing Hohner Products…Because that’s what I began in 1977…
