Hi, I've been playing a 4-string fretted Precision Bass for about 15 years. I'm a decent player... no slapping just groove rock. Anyway, I'm purchasing a new 5-string bass soon but I'd like to have the best of both worlds if possible. I've always wanted a fretless. Would a 5-string fretless be too much to master given the instrument I'm used to? Either one (a fretless or 5-string) doesn't bother me... it's the two of them together that makes me wonder if it's a good idea Thanks for your input!
