First introduced in the arcades as an enhancement to the popular Konami simulation game, "2nd Mix" updates the musical library with a total of 45 tracks ranging from flamenco to fusion rock guitar pieces. It requires the original Guitar Freaks disc, as well as near-mastery of the original game.
Each mode start out with 16 tracks right away instead of 6 in the original. The layout for song selection is a little different in that the song titles appear horizontally on a menu and you select them by scrolling up and down.
You have a guitar controller, which consists of three colored buttons at the top, and a small flipper placed where you would normally pick the strings. Guitar Freaks has a vertical bar staff that consists of three bars, color-coded to coordinate with the buttons on the guitar. As the notes reach the top of the staff, you must strum on the guitar while holding the coordinating button.
