Mac,

Now there's an idea: a fretless nylon. Every so often, I've heard of guys playing fretless guitars, or fingerboards that are scalloped instead of equipped with frets. Then there's Charlie Hunter who plays an 8-string guitar using a (nonparallel) fretting system that lets him play bass on the top three strings. Few have followed in these directions, though.
