The surprise success of
Guitar Hero readily led to the development of a sequel for the game.
[10] :According to developer John Tam, the team felt they "hit the sweet spot" of genres and decades within the set list and wanted to maintain that for the sequel.
[10] The costs of obtaining licensing rights for music from "big bands" such as
AC/DC,
Led Zeppelin,
Van Halen, and
Metallica, in addition to the lack of understanding of how the music would be used prevented these groups from being used in
Guitar Hero. However, Tam notes that with the success of
Guitar Hero, "They understand that we're not going to embarrass their music, we're going to actually pay homage to their music and get it to the point where people are going to fall in love with their music and understand their music in a totally different way than they've ever experienced it before."
[10] They also had requests by artists to include master tracks within the game.
[10]In addition to working more directly with artists, RedOctane and Activision worked with various musical instrument and equipment companies to provide in-game
product placement. Such vendors include BOSS Effectors, DW Drums, Eden Bass Amplication, EMG,
Epiphone, Ernie Ball Strings,
Gibson Guitar Corporation,
Guitar Center,
Hofner, Kramer, Krank, Line 6, Mesa Boogie, MusicMan Basses,
Orange Amplifiers,
Randall Amplifiers, Roland, Vans and the Vans Warped Tour, VHT, and Zildjian.
