Man, I would trust what you read that no USA bodies were made of basswood. I've never heard of basswood USA Kramers. Also I do not believe that the smell of that wood is going to tell you much about it after all these years. My artist friend Jake has been getting into pyrography (wood burning art), and he works most often on basswood because it takes the burn really well. I've been around a bunch of pieces while he was working on them, and I can tell you that after it's been dried, basswood doesn't smell any different than any other wood. I've actually got a piece of it right here in front of me as we are experimenting with different types of clear coat to look best with the pyrography.
Here is his instagram, you should check out his shit for a minute; pretty awesome talent he has. He's only been doing pyrography a very short while and he is getting his technique dialed in better and better with each new piece; I can't wait to see where he takes it in the future!https://www.instagram.com/robbed_of_reason/?hl=en
