the Bass Expansion for its educational guitar game, Rocksmith, is arriving on the PC on October 16. The DLC pack, which includes bass tracks and teaching functions for either a standard 6-string guitar or a 4-string bass guitar, hit Xbox 360 and PS3 earlier this August.
In addition to content for the game's current songs, the Bass Expansion allows you to access bass information for any DLC songs in the future, so it's quite an investment. The Bass Expansion will be available for $29.99, the same initial price as the console versions. One important bass-playing thing it won't teach you is how to look cooler than the lead guitarist while you play. Better get started working on that right now.
