Has anyone found any free or cheap resources. Am aware I can use piano, guitar, etc. to play my 1962 Italian made Borsini. Am planning on buying another Hohner. Made mistake of loaning my Parelli (spelling prob wrong) to son and it got wet in plumbing leak. No worries. It was used and am now able to select exactly what I want w/Hohner’s assistance. Very excited! Merry Xmas to me!!! lol. Again any advice welcome and much appreciated. Blessings to all!
