Different amp setting for different parts?

[sgt.pepper]

Hey do you use different settings on your guitar / bass amps for different song parts?

Just like more or less gain in verses or choruses? maybe some mid boosts / cuts?

Or do you record a whole song with the exact same settings?

live...sometimes if i can change my settings i do - eg for feedback sustain krank up the gain on my peavey (live)

when mixing well yea i would sometimes change my tone per part for dynamics. eg pre choruses i usually roll back on the gain so that when my chorus kicks in its nicely saturated, creamy and crushing
