I think the left hand has a lot to do with it. I've watched Sacred-Steeler Chuck Campbell up close and he explained the technique.
The bar is lifted up off the stings much more than we do. The bar comes down and hits the strings as they are being picked, even in fast single note runs.
This produces a slight percussive sound, similar to a standard blues/rock guitar player.
They don't use a round bar. The bar looks like a large Dobro (Stephens?) bar.
Unfortunatly, the ACL show you are all talking abiut was not broadcast here.
