My thoughts exactly. At the end of the day if it hasn't worked, I haven't lost anything but some time and some workshop consumables. It was an interesting exercise regardless of the outcome.
After seeing how the truss rod works in these, it's hard not to think the two way ones like I used in the Deluxester and what I think must be in the PBG necks are vastly superior.
It's still holding adjustment this morning. Will do some more fine tuning of the setup today and then just keep an eye on it.
