Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!
I recently made a halfvalved diatonic with a GOLDEN MELODY HARMONICA. I’m having a tough time bending number 6 blow bend. All the rest work great. Any ideas?
