Re: [Harp-L] Re TUNing Reeds

When you heat them that way, it discolors the brass, you get various bluish hues. The Seydel Solist and Favorite and Favorite Black from around 2006, have those same hues on the reeds. You don't see those on stuff made later.  I figure Seydel came to the same conclusion I did, too much trouble.

I can't remember the exact details but it had to be really hot and it took some time.
