Fender 5's are not bad IMO. They are quite inconsistent, but (again IME) so are most 5 strings especially. If you are looking for a 5 jazz type bass they are always worth playing/trying when you see one. I stumbled across mine and it's a decent 5 string, and has stayed with me as a back up to my celinder 5. It's a deluxe 2010 model (blocks/binding). It does the job as well as basses I've played 3 times the price. It is also DEAD reliable. I have played lots I didn't like, but I think there are good/great ones out there.
What is disappointing is the build quality you notice under the pickguard. I mean this is Fenders 'benchmark' high end workmanship, end they route the neck pickup and keep the tool spinning right down to the electronics cavity through the middle of the body! Horrible, and clearly budget orientated. You can't take the guard off, it's more of a plaster on that scar than a guard to protect the finish. They need to sort that out IMO in this day and age, and with superb competition from Lakland, Sandberg, Mayones etc.. It's arrogant to think they can get away with it.
That aside, worth playing them if you're shopping, one might take you by surprise.
