Yep, you should definitly use the resonator guitar.
There was this blind guy that used to play out in front of a little restaurant in Greenwood MS when I was a kid spending time a few summers at my grandfather's uncle's place in Tchula. We'd go there cause it was the big city.
Anyway, this black guy played a chrome National with a cup on the end of the peghead. A harmonica too. Wish I'd have paid more attention, I remember him as big real good. There I was, right there at the crossroads and didn't even know it.
