Well, I've had the fretless for a few months now and I'm really enjoying it. My intonation is still pretty sketchy in the upper portion of the neck. Are there any techniques (adding little pieces of tape, etc.) you would recommend I use to help in the process or do I just need to keep at it? It sure would be easier to have lines, but the advice of many has been that I won't need them after a while and I would wish they would go away. By the way, of the fretless players, do most play unlined?
