I have a 4 string squire P/J laying around that I am not using too much lately, and was thinking about defretting it. My main problem at this point is whether it's going to be worth it. I play in mostly rock bands and jams. I am only 17 and this is a big investment for me because I would need to pay for the defret (I wouldn't trust myself to do it) and then pay for some new strings and maybe even a new bridge pup (Seymor Duncan probably). This is a lot of cash, and I want to know if it would be worth it to start learning fretless. How long did it take most of you guys to start getting the hang of it? If it takes a long time I may start now but I don't see me playing fretless as a main bass anytime in the future, and it would only be a play thing. Do you guys think it would be better to wait or should I start learning fretless right away?
