Can I apply different amplifiers to sections of the same guitar track? I have even split the track into 2 and made the selections but it seems to play the entire track with the last selected amp. Thanks!
No, it's always one track, one instrument setting (you can automate the parameters of that setting with a curve though. If you want to have two different guitar sounds, use two separate tracks. That's better anyway, you can modify things like volume and EQ independently for the two sounds in the mix.
