I am thinking about switching overe to Fretless, as no one around here where i live plays or can play one. I am pretty good at Fretted Bass, but am thinking about taking up a challenge. Now how should i practice fretless? Should i just play my fretted with my eyes closed or what? And how long did it take for you to learn to play a fretless well? I'm not sure if i am ready for the switch yet.
