ANyone use these? How about the tone? As compared to my lovable Fender Jazz bass 4 tone which I can not seem to beat. Do the Roscoes have a good slap and bite tone like a Jazz? How are there playability as compared to a Smith 6 neckthrough or R bass 5 neck through? Sorry for all the questions. I am thinking about plunging into a 6 string and Roscoe seems to be the only bass I have not ever played on.
