A Familiar Friend: Rock Band Guitar and Bass

The Rock Band controller doubles as bass and guitar, but the box only comes with one.

­The guitar and the bass peripherals both work on the same controller. Similar in design to the Guitar Hero controller, the Rock Band guitar/bass looks more like the real thing since the fret buttons are camouflaged with the color-coding along the side of the neck, rather than the top.

As with the other hardware, operating the guitar/bass is all about timing. The fret buttons select the note, and the strum bar executes the timing. The lever inside of the strum bar sets off an electrical chain reaction that communicates to the software the note you just played.

Guitar Controller Snafu
As mentioned on the previous page, when you purchase Rock Band, you get one guitar controller. Since the bass and the guitar work off the same controller, that means you need another one to complete the square of your rocking foursome. This leaves Guitar Hero fans at an advantage because they can simply plug in their old Gibson styled controller. Right? Not so fast. Neither Activision nor Harmonix wants to give free products to each other, leading to peripheral compatibility issues.

According to Joystiq.com, the only console that will allow you to use your Guitar Hero 2 and 3 controllers for Rock Band is Xbox 360 [source: Miller]. PlayStation 3 and Wii users will have to buy an additional axe from Harmonix. The Rock Band controller also isn't compatible with any Guitar Hero games. ­

­The Rock Band guitar also has a second set of fret buttons near the body. These activate during the solo sections of the songs when rockers can wail to their hearts' content. You can also use the whammy bar to give sustained notes a "wah-wah" quality. Spicing up the familiar Rock Band controller, you also have a pick-up switch at your disposal that can make five different sound effects during solos and overdrive, which you'll learn about later.

­Music data for each of the songs -- broken out into mic, drums, bass and guitar -- are stored as waveform files [source: Yoshitomi et al]. Waveforms store the music as disparate sections, which is how the game can judge when you've royally missed or hit a note. Depending on the mode and instruments you select to play, the software will pull the corresponding waveform files to allow you to either play solo or with three other people.
