At this stage of my bass playing career, I would prefer to use a P/J 4 string fretted, a 4 string fretless and a 6 string jazz bass. I just need to replace my 4 string fender jazz to a 6 string lol. I can cover 95% of the songs in my band with my 4 string P/J but at time I wish I have a 6 string and the odd songs my fretless will be called.
