Watch the Full-Arm Swing online guitar lesson by Rich Maloof from 50 Acoustic Guitar Licks You MUST Know

Pete Townshend ("Goin' Mobile") , George Harrison ("My Sweet Lord"), Tom Petty ("Won't Back Down") and plenty more like 'em have achieved a huge acoustic sound by strumming all six strings and strumming hard over a progression of barre chords. Even if you get some rattle and buzz in your barre chords, all is forgiven when you're knocking out great changes in a big, strummy rhythm. For best results, let your elbow be the pivot point on the strumming arm, get a tight grip on those barre chords, and don't hold back.
