Johnny Winter's acoustic slide songs sound best on metal body resonator guitars.
Judging from the covers of his albums he played a National tricone on The
Progressive Blues Experiment and Nothin' But The Blues and a
National single cone model on Third Degree. They sure sound good on my
'37 National Duolian. I agree completely with his opinion on Nationals:
I fell in love with that nasty sound. It reminds me of a garbage can with wire on it.It's got all that metal ring to it, a real bluesy sound.
He usually plays with a thumb- and a fingerpick and wears a metal slide on his little finger.
