The phenomena that is Guitar Hero now comes to you in a portable, pocket-size version, but keeps all the fun and excitement of the original. This miniature Guitar Hero has three levels of difficulty and five levels of volume. To become the Guitar Hero, beat 3 riffs to advance to the next bracket; beat all 3 brackets to reach the final number! It measures approximately 1" x 3" x 7-3/4" and the bottom has a spring clip to easily add on to a keychain, keyring, belt loop, etc. Make sure to press the whammy bar (button) on long notes to score even more points!
