Like Lamb of God drummer Chris Adler, Campbell is a vegetarian. John is a proud graduate of Fishburne Military School in Waynesboro, Virginia. Unlike many bass players who will use four and five string basses, Campbell at one time played a self modified three-stringed Guild Pilot bass, excluding the higher G-string.
