+1 for the notched straight edge.
I started dabbling with set ups and bought the Music Nomad feeler gauges. These indicated the correct truss-rod tension, but I was still getting problems. With the straight edge, I could take the relief down (almost a flat neck) and the problems are gone and it’s easier to play.
My current thinking is ignore truss adjustment based on string height. Just get the neck as flat as I can without creating fret buzz.
That’s what I wondered.
Even if the new pick ups don’t have stronger magnets, I guess lighter strings could get pulled on more easily…? Or maybe the new strings have a higher iron content and are more prone to magnetic pool? (as I write this is sounding less plausible!).
