I recently did a little shifting with the neck of my Ibanez ATK and found something I didn't expect. At the base of the neck, there are only supposed to be five holes for the five bolts, right? But for some reason, there is a complete sixth hole and a partial seventh hole that were drilled in completely random positions. But it doesn't stop there: right in the neck pocket, there is another extra screw hole. It doesn't make sense to me why these extra holes are there, and it makes me upset that quality control would have let them slip. It also seems that one of the screwholes isn't completely straight. With all these problems, it's fair to say that I have a faulty instrument. Should I try and get it replaced, or is it not worth it?
