That's actually exactly why most of my guitars have darkbursts and godwoods, and the ones that have higher output pickups have been tested with those PAF style pickups first. I 1000% agree that if the guitar doesn't have good "guts," nothing will mask it; and that goes doubly so for going into a Larry, lol. I do run the Larry with an assortment of good speakers, but I'm actually doing some experimentation right now on that, too. I've kind of "proved" to myself that I can get Schaffer-esque tones, now I need to figure out what works for my own playing style.
The YouTube autists can spout all the GIGO science they want; I've learned through hard-earned experience that not only are you right, but that you're right and it makes a huge difference, especially for certain types of guitars.
