Yup, I use a rack. Plenty of times it's just to add a different "voice" to my sets. Often I'll just play more melody, but I have a few tunes where I play cross harp for more of a bluesy feel. You do give up some tone playing with a rack; can't do all that expressive stuff with your hands. But i haven't been busted yet, so I guess that's a good sign. It does seem there are different rules for different genres; folkies tend to get away with more it seems, thaan blues players. I'm in awe of the latter; how DO they get all those notes outta that lil thang??    sb
