I have played the bridge of my song with power chords using audio, acoustic guitar through the mic. The progression came out well in Logic. But I feel it could sound better. Yes I want to emulate or reproduce guitar power chords in Logic with a software instrument?
You could use the EXS24 Instrument. There are Acoustic & Electric Guitar presets in there.
You could also apply some of Logic's Pedalboard effects to the EXS24 instrument for a more closer guitar effect.
Then draw in the notes for the power chords in the Piano Editor.
