I just did this yesterday, and I'm only listening to the results now, so I'll reserve any opinions about any particular guitar, but I will mention why I did this, and what has been surprising to me so far in the results.
Instantaneous comparison When trying to evaluate different components of a guitar's tone, even the 5 second lapse while you switch guitars is enough to muddy your perceptions. Being able to switch signals instantly in a loop of the same riff reveals the "truth" about individual components of tone.
Not distracted by the act of playing Being able to simply listen and not have half your brain devoted to the act of playing allows you to focus on what you're hearing.
Quantitative analysis Ultimately, tone exists in the ears (or brain most accurately), but being able to see the db levels, the amount of amplitude variability, and the EQ curve is a powerful tool.
What have I noticed with all of this objectivity? It's early days, and I want to dig into this data a lot before hopefully pulling some useful insights from it, but I have noticed a few things.
Relative relationships between pick ups color subjective perceptions and hide absolute qualities.
My telecaster has a dual blade, bar magnet hum bucker in the neck position. Compared to the bridge pickup of the telecaster, it's pretty "dark." however, compared to the other neck pick ups, it actually stands out amongst the brightest and most articulate.
The ES-335 has huge output levels, but a surprisingly broad and useful EQ curve. Swapping between the 335 and other guitars in person, I waste a lot of time adjusting my ears and my amp to its higher output level. But when the jump can be made instantly, and the gain can be normalized, you realize that it has a frequency response that's a lot more delicate and "scooped" than you might expect. Certainly when compared to the Sheraton with its epiphone "dum"buckers.
"We might be looking for the same thing..."
Instantly jumping between guitars reveals some as icepicky and quiet and others as muddy and oversaturated. In both cases however, the amp and other elements are adjusted to bring them closer to each other. The amount of saturated and EQ that's desired is about the same in most cases. What would be interesting is seeing which guitars embody those qualities best without any adjustments.
Which means
Most signals can be made useable. For a "solid" middle of the road tone, even the muddiest and most trebly sounds can be squished and beaten to fit the mould. The real issue then becomes those situations when you want "more" of some quality. The naked pickup tone started out so far skewed in one direction, that it doesn't have any adjustability left to reach those outlier tones.
