Ok, I'm reading a lot about fretless here, but I can't seem to really figure out the answer (or clarification) to this question... True Fretless, you put your finger in between the "frets". Meaning, if there is a dot on the top edge of the board, you'd either place your finger in front or behind the dot. Lined Fretless, you'd play (put your finger) right on the line (the fret marker). True??
