I like the sound of Willie Nelson's guitar. I don't have a Martin classical with a hole worn thru it,but that's besid the point. I know he uses nylon strings with ball ends.I'm all thumbs when it comes to tying nylon strings together. I can tie tiny line to a tiny fishing fly or lure,but I can't tie nylon strings very good.From picures I've seen of his brand of strings,they look to be a pretty good set. Any ideas on what brand he uses?
