This may sound like a silly answer, but hear me out.
Watch film clips... preferably live ones.
They not only show you a guitar, but you can see if they are new looking or like they have been around for a while (relic 'ed guitars were not a real thing with musicians back then... they looked old because they were).
When you look at the guitar, notice how many pickups, what position his toggles are in and whether they go into pedals, or straight to an amp. At this point, notice the amp. What brand and how he has it set... up high or on the floor... these are factors that effect how he uses it.
If the guitar has modifications, you can almost guarantee they were put in by him... and will be used.
Obviously, if there are pedals, attempt to identify them and observe their most probable order.
Now watch him play.
Gentle picking and volume knob work change how his sound comes across. If you want to sound like him, mimic his style and you will get closer.
Of course, then there are mics and positions and techniques used in recordings that none of us will ever really know about, but these are great starting points.
