Marshall Amplifier Stacks
Of course, electric guitars can't rock without amplified sound.
Enter the Marshall amplifier, which started out as a copy of a Fender Bassman amp but ended up with a "roaring" sound of its own, attracting the attention of musicians like Jimi Hendrix, Eric Clapton, and The Who. But why stop at one? Marshall amplifiers travel in packs, like the three-by-six stack shown here, used by the heavy-metal band Slayer.
The stack started with The Who, but it quickly became so popular with performers that a wall of Marshall amps is now synonymous with rock . In fact, many concert setups have several racks of Marshall amplifiers that aren't actually powered because the speaker overload would wreak havoc on the show's acoustics.
