Hi folks. I recently was given an old beat up, bitsa no-name, filthy fretless. I've cleaned it up now, put new flats on it and it actually feels and sounds quite good. Problem: I've never really played fretless before and am struggling a bit (a lot if I'm honest). The board has lines however they're pretty hard to see and the side markings are more or less invisible. So, good people of basschat, some tips for learning to play this thing would be brilliant. Thanks in advance.
