Funny- I bought these exact same parts from a chain hardware store for a third of this price (maybe less). Rather than draw on my "years of experience/product development", I just copied exactly the machine screw/insert neck attachment of my old 1981 Ibanez Studio bass...I can't believe anyone would be silly enough to fall for this. I guess I can say that at least the buyer would actually be getting the parts for a solid neck joint- just at a huge markup and with a whole lot of BS hyping. In one of the replies to a question about the "kit", he essentially says that he has all the peices custom made...
Besides, everybody knows that neither screw nor machine bolt can compare to my patented "Krazy Glue (tm)" neck joint- available to you for only $150 shipped and with enough for multiple necks!
Check out this "amazing" new product...
