If you are playing in a way that requires high action that’s one thing. But as I said there is no tonal or volume benefit.
It’s just another one of those fallacies that keeps on getting repeated.
Well, descriptions of "high" and "low" action can be loaded. How low is your action? People even add fall away -- or different relief on treble vs bass sides via plek -- for partly similar reasons to typical string height adjustments (partly different effect, but still).
I certainly don't think it's a fallacy that higher action, all things being equal, at least from some threshold and on, helps the guitar sound "cleaner", including getting cleaner bends.
You can give the same guitar to 2 people. For the first, it buzzes -- even plugged in. For the second, it hardly does. Playing technique matters. Not just slide playing imo, even if a certain threshold tends to be more important for slide playing.
And there may be a certain threshold of technique, settings, set up -- whatever variables are in play -- where the specific difference in string height made not much of a difference for you.
Never mind that this charvel is a guitar which you weren't familiar with at a lower string height, I would assume?
I'm not doubting that for you there are was no big or meaningful difference, as an experience. But switching between guitars can alter enough variables to throw off such testing.
If you have a 7.5 inch radius you'll eventually reach a point where you won't be able to do 3 semi tone bends, as action gets lower, other variables consistent. That alone can be quite an issue and one of the reasons why people started doing flatter and even compound radius fretboards.
But it's also perfectly possible that someone doesn't bend as far, and doesn't pick hard enough, so all is ok.. or another person does pick hard -- and the guitar starts sounding and feeling more and more choked from a certain threshold and on.
Maybe people at times exagerate the difference "all" thresholds and changes make. It's surely more nuanced than that. But string height can certainly be important.
