Mark Tremonti rocks but he is also tricky, I played and tabbed the solo of Alterbridge "Open your Eyes" in the Standard guitar tuning E-A-D-G-B-E, and mastered it for a while, only to find out that he played it in an Alternate tuning of Drop D5, Im really disapponted because everytime I like to play that song or their other songs, I will have to tune down my guitar to their tuning, and you need to tune down all strings and not just the high E string, because of that wierd tunings.

Still Tremonti is very good right now, But I think he should refrain from using unnecessary drop tunings, any way they have a vocalist in Miles Kennedy who can sing at any key which is unlike Scott Stapp who can only sing at D or drop D. In that way many guitarist can play their songs and spread the news.
