Err, right, Huang harps...

All I can find out about Huang Frontier harps is that this name was given to a ten-hole blues harp-style model. But you say 48 holes...that sounds suspiciously like a tremolo harp of some kind.

Now for the bad news. Huang harps do not have a good name among harmonica players. Whilst they are inexpensive, they tend to suffer from execrable quality control. I've owned several, and still have a Star Performer that I dig out on those rare occasions when I need a B flat harp, but my experiences have not been happy. I've had to spend time retuning reeds and setting gaps in order to get the things to play at all, and they don't last. I've had problems with the metal plating of the covers of a Star Performer breaking up into extremely thin, sharp metal shards that cut my mouth. If you've had yours for that long and it still plays in tune with nice, even response, you can probably count yourself lucky. If it were mine I wouldn't waste too much time on it. But it isn't, and you're not me!

When you say a reed isn't working properly, what's it doing wrong?
