One's man's good tone is another man's crap tone when it comes to National. Many people hate the steel tone, I like it. But the brass models Like the Type O seem to have more musicality across the board and seem to be more versatile. I personally think the metal bodied tri-cones are the most versatile of all Nationals as they have a complex tone great for single note lines and fingerpicking, but you can still get a good metal bodied blues tone out of them. Though if you are a hard core bluesman the steel ones have a punch that I feel just can't be beat. I own a modern triolian that just kills for that kind of stuff. And if that's what you do I would check out a triolian. here's mine...
