It means:
a) "in some cases"
So, for example, somebody with a light touch
b ) "it can accomplish"
A successful result can be reached
c) "the same goal as a compensated nut"
Both are aimed at doing the same thing, which is to minimize intonation problems
d) "which is to reduce the impact of fretting a note on a string's pitch"
See above.
It's pretty clear English.
I didn't say they have exactly the same success rate, and nor did I say they were directly compatible. They DO share a common goal, and the degree to which they're successful will depend on different things.
If your contention is that a compensated nut FIXES the problem, then I would have to disagree. Maybe yours do, for your guitar, in your shop, but for somebody buying an Earvana, mileage may vary. And an Earvana IS a compensated nut, a respected one, and a heavily sold one. But if you can tell me that its compensation will be consistent for every single guitar out there (obviously, other factors such as a plain old shitty guitar that will NEVER be in tune aside) then I'd have to concede the point. But I think you'll find that from guitar to guitar, player to player, and string guage to string guage, that a compensated nut ALSO only words to "reduce" the impact of fretting a string.
Both systems can ONLY reduce, not completely "fix" the problem. That's the nature of a guitar.
If you say that a compensated nut is BETTER for the job, I haven't disagreed. As far back as page 3, I've consistently agreed with this point, and THAT's why I say we're not in disagreement.
As for the getting riled up: only a poorly-tempered person would get riled up over the nut argument, that's for sure. Which is why I think your choice of when and where to capitalize and when and where to use triple question marks could have been better thought out. I'm certain I'm not the only person who would interpret that post as adversarial.
