ELI5: Why do guitarists sometimes use different guitars for certain songs causing them to switch instruments mid-set?
gpt
besides the different tunings, different guitars have different sounds.  Guitars are made of different materials, different woods, different pickups (which capture the vibrations of the string), and different circuitry inside of the guitar and pickups. So a guitarist may want a "Strat" sound for one song and, say, a Les Paul sound for another.
