When I was a working musician, I used my Fender fretless almost exclusively. Then we starte to do some funk, and it sort of ran out of zip. So I got an Electra Jazz copy. For the few songs in which frets were a plus, it did the job nicely. Currently, I own 3 basses and play them in rotation. The fretless Jazz for improv and blues, the Kawai for jazzier, more progressive stuff, and the Precision Deluxe for funk and rock. The trio has quite a bit of flexibility in tone.
