I just saw Lamb of God for the 4th time the other night at Ozzfest. I noticed that Mark was using EMGs instead of his usual Seymour Duncans. I didn't see whether or not Willie had switched either. Anyone else notice this?
Ya same here noticed it when i saw them Aug 1st.
It says on his wikipedia article that the band endorses EMG products onstage.
There is an Only Lamb Of God thread here: https://www.ultimate-guitar.com/forum/showthread.php?p=10405633#post10405633
