Hi again
well, three years down the line from the original post, I did finally get hold of a Martin nylon string guitar 00-28, from about 1956. It is a lovely guitar for finger playing and sounds good through an amp. And guess what? I sound nothing like Willie Nelson, and never will. There'll never be another, and if there were it wouldn't be me, that's for sure.

Playing arpeggiated chords sounds good on this guitar, lovely for accompanying singing.

Thanks for all those views, and advice.
