What are some advantages of the fretless bass? I could see if you are soloing you would be able to do more with a fretless but for normal playing I dont see the advantage. I have been listening to Gary Willis a lot lately and it seems like most of what he is playing could be done on a fretted bass just as well. By the way, lets hear from all the Willis fans out there. That man can jam! Is a fretless something that every bass player should explore or is it such a specialized instrument that most would not get much use out of it? Please educate me.
