Went to the Metallica concert last night in Atlanta at the Phillips Arena. It was crazy,had an amazing time. Rob had some crazy basses last night,one of them that really stuck out in my mind was a warwick streamer. He must have had it custom made had a fairly thin neck on it. Here's a picture of it from last night. He also had a really nice vintage P bass he used on their older songs EDIT: FYI I did not take these photos.
