I'm comparing my options for a fretless bass, and one of the basses I'm considering is the G&L L-2000. Has anyone played one, fretted or fretless? How does it compare to the JB-2 or the Fender equivalents of each bass? Blah blah blah? Seeing as I can go for a MIM Jazz for about half the price, I'd like to know if I'm getting a nice bass or not.
