Hey all you fretless players I have a question for you. How long was it after you started to play bass that you were able to comfortably move to a fretless bass? What changes were involved and what were some challenges you faced? Since I've never played a fretless before, excuse this question but does the technique involve being able to visualize where all the frets are at to be able to play one or is your technique different?? As always, thanks for everyones help!
