i was gettin the problem in fig 4 on the second link you posted. ive done sum research, the neck is level so dont need to adjust truss rod. Im gona raise the bridge up a few turns so i have a bit of downward adjustment. Then place a shime about 1.5 - 2mm in between the neck and body, im gona try and find sum hard wood for this. Re string it and lower the bridge until it feels and plays good with no fret buzz.
Prob take the day monday to sort it and try set it up...
Im new to guitar set up, so going to learn it on this guitar.
