Ive noticed how many bands have many songs they play live, yet some are in different tunings. How do they tune down/up without manually tuning? Because they never mess with the tuning pegs and it would be too hard for some songs to just move up/down so many frets.
You have 2 choices. 1 you manuallly turn ur guitar usually using a tuner either onboard guitar tuner or one in your effects loop. 2 you have multiple guitars in multiple tunings. All my bands music is in drop C usually so you wouldnt have to do any tuning but my solo stuff is all acoustic so i just use my onboard tuner on my guitar.
