Re: [Harp-L] Reeds

[Steve Webb <swebb@xxxxxxxxxxx>]

I have tried all kinds of things experimenting with gapping diatonics. At one point I thought the reed needed to dip into the slot and curve upward. I am still never sure just how to gap. I mess with draw and blow gaps until I find something that works. I would much prefer to find a method that would be faster and more accurate. 
The only mods I do are gapping and embossing. I have a couple of combs from Hetrick and am going to see if that makes a difference. I play mostly Sp 20s, but have some Delta Frosts and Seidels too.
