Palm muting is more effective on a les paul type bridge, than on a strat bridge.
If you fret an E minor on the second fret( left hand ) and rest your right hand on the bridge with the bottom of your palm and wack the bass strings - it's most effective with heavy distortion - it produces a musical type drumming sound.
You can also try the same technique with a second fret A chord and any other chords on the three bass strings
