If you set your string action by ensuring the bottoms of each string are a consistent distance from the frets, doesn’t that mean the tops of the strings are now inconsistent because of the different string diameters? Is this a problem? Do you need to be concerned?
Another look at the integrated saddle/piezo pickup. You’ll most often find these in Takamine guitars but there are variants around. Like this Epiphone pickup. The action needed a little finessing here and this version presented it’s own challenges.
