Just got my first fretless (Fender American Jazz) after 16 years of playing only fretted basses and now I'm kicking myself for not getting one sooner. I can get the same punchy tone that I do out of my fretted instruments as well as get more expressiveness with vibrato and slides. Plus, I can set the action ultra-low and not get any buzz! Intonation isn't an issue as this bass has fretlines. I bought this instrument as a supplement to the rest of my basses, but I foresee using this bass pretty exclusively in the future. Only issue so far is an A-string nut slot that is cut too low which is causing a rattle on the open string. I'm taking the bass to my luthier tomorrow to have him shim up the nut.
