Hiya Dave!!! Hartley
As a musician, man, you are sharp! I cant sneak anything by you!
Let me try to address some of your observations!
1. Sound. That raspy sound, is an sound of desperation. I just get lucky sometimes, with the inexpensive equiptment I use. But so did Motown, in its early years. It is what it is, and nothing more.
2. Bar Hopping?

Had a different meaning back when I was a young sprout! But I know what you mean now! And you are right. I use a Stevens Bar, that is used by a lot of dobrow players. For me I never could play with a Bullet Bar. My hands perspire, and now, some arthritis, has become my advisary these days.
3. Yes, I close my eyes, especially when I dont want to see what a mess I`m making with my attemps at trying to play the song, that I`m trying to play.

Naaaw! It does happen that way when I "feel" the music, that nothing else matters, as it flows from the heart/soul. I guess that is why it is sometimes referred to as "Soul" music.
At any rate, I`m just happy to know that the music makes somebody "smile". That is what I am all about. Be blessed, my friend, and thanks for asking!
