Here's my newest wild idea. Is it possible to install fretwire so small that I get the best of both worlds? Intonation accuracy from the frets and the sound from the wood? I want a lined fretless anyway--just make the lines out of fretwire that's maybe 1/4 the height of normal frets? Have you ever experimented with this concept? BTW: What's the best wood for a fretless board?
