i have four harps
a hohner blues harp (wood)in c
a hohner mirine band(wood) in f
a hohner special 20 (plastic in b
and a hohner hot metal (plastic ) in a

my hot metal broke in 2 weeks, i tryed cleaning it and all sorts of stuff and it just woodnt work, my special 20s acting up now , it stil plays, but reeeeaaal quiet, my blues harp (my first harp) works fine, as with my mirone band, but the other 2 are trouble

Well,if the metallic parts are broken,you will buy other parts...here in spain if you got the harp broken,you would buy a new harp :(
