I need some advice on how to fix. It is on an A harp. I was going to use an angle grinder to take some off the short end of the reed. Maybe a blow torch. hehe.
I was really thinking like an Emory board or nail file. I think I remember Gussow talking about it on a youtube episode, but I can't find it.
I used my guitar to tell that is about a quarter step sharp. Maybe less.
(Edit: Kingley beat me to the punch while I was typing the below response, but there might be something in my post useful to you anyway so I'll leave it as is)
Be a bit careful with tuning to a guitar, because most harps are tuned up to 442-445 Hz ( not 440 Hz ), because when you draw hard it will flatten the note with the pressure. Then also the reed could be tuned up or down up to 10 or 12 cents depending on the tuning scheme of the harp.
Anyway if youve got that sorted most people will use a jewellers file, you could also just stick some fine sandpaper onto a icy pole stick. File the tip to sharpen, and the base to flatten the reed. You can also use a scraper to remove material from the base of the reed to flatten it. From memory I think a guy on Youtube Hakanehn might have a vid showing some tuning.
