With the Fender Player Series Jazz Bass Lefthand Neck PF,
Fender Player Series Jazz Bass Lefthand Neck PFI really can't complain about the quality of the neck. Small details like the four pre-drilled holes per tuners were unnecessary in my opinion, as they simply didn't fit the Jazz bass tuners I had. I had to drill more holes. But that's all right, because you can't even see them.
The unexpected part was that I needed a 3/16" hex wrench for the truss rod (not 4mm, used in the guitars made in the EU or Indonesia). This makes sense and is one of those "if you know — you know" things. But it'd be great if this was mentioned in the product specs. I, at least, would purchase one in advanced.
