all you do it make a power chord on the 5th fret with the pointer on the 5 and you pinky and ring on the each on the two 7s. then you just mute the strings on the just 5s and play unmuted on the full power chord parts.
Gear:
Gibson SG w/ Bare Knuckle Aftermaths
Early 90s Fender MIM Telecaster
Squier VM Jaguar
Ibanez RGD7421
