The Thunderbox Amp 28r allows Guitar Hero players to enjoy the rich sound of a real guitar amp that's been especially designed for use with the game. The first and only guitar amp available for play with Guitar Hero, the Thunderbox Amp 28r provides an unmatched level of realism and excitement as the distorted crunch of chunky rhythm parts and soaring tones of blistering guitar solos blast out of the player's own 30-watt guitar amplifier. And the Thunderbox Amp 28r is no toy--it's an honest-to-goodness guitar amplifier with 1/4" inputs for use with real electric guitars, microphones and more. It provides a monster sound from its low-profile cabinet design, and it includes a master volume control and two independent channel volume knobs as well as controls for treble and bass. Its silver face plate and tweed grille cloth are reminiscent of the famous silver face suitcase amps used by famous artists, and its 6.5" bass speaker and dual 1.5" speakers deliver a powerful rocking sound over a frequency spectrum of 35-20kHz.
