I have liked jazz for a long time, but I took out a Jaco CD about a week ago, and now I am in love with jazz. I'm learning Portrait of Tracy now, and I just can't get enough. I have had my eyes set on a Warwick fretless bass for a while now, but after hearing Jaco's tone, I am re-thinking my choice. I am also into Les Claypool and Primus, so that influence is also pushing me towards a fretless. I have heard that the Warwick Corvette has more of a bright "mwah" tone than an American Fender Fretless Jazz, but the Fender has a really punchy tone. Which one would you choose?
