Listening to the track TNT by acdc and trying to play along with it it almost sounds as if it has an alternate tuning like a half step down or something like that would anybody known anything about this?
it just sounds like that because the tapes were slowed down in mixing, thus create a slightly flat tone. Its like a 1/4 step down i think. Most of their tracks were mixed in that way during that era. Just use a pitch changer, such as the one in Audacity and increase the pitch to standard. Easier than tuning your guitar to the song. Hope that helps.
