Great option for a serious fretless bass
This is a solid, really high quality instrument with a few details that make it stand out, and at a price that is relatively accessible for a professional quality bass: nicely voiced, traditional sounding passive J pickups, beautiful, classic looks (I've put the pick guard on and will put standard J bass knobs on), great playing, easily adjustable, a nitro finish, and well balanced (mine is 9 lbs).
The instrument's finish is fantastic, really well done in nitrocellulose lacquer, and the joint in the two-piece body is indistinguishable. Here, especially with a transparent finish, the fact that Sweetwater has photos of the actual instrument is critical if you're buying something on-line.
It was playable out of the box, and with minimal truss rod adjustment, new strings (still flats, my preference) and no bridge saddle adjustment I've gotten it playing as I like it. The neck and fingerboard both feel really good to me. I have two fretted Jazz Basses, so this is familiar to me. The pickups sound like they should, the bass feels and looks great. Should be near the top of anyone's list of high-quality 4-string fretless basses, and obviously is at the top for me.
With Fender, as with pretty much any other maker in my experience, quality and qualities like feel vary from instrument to instrument. They're made of wood and are built with some to a lot of human craftsmanship, and things like weight, location and intensity of dead spots (wolf tones), neck pocket fit (an overemphasized issue IMO), and even the peghead profile vary. I find most higher-end Fender instruments to be really flexible and adjustable, and this one is no exception.
