It's first entry into popular culture was its appearance on Muse singer Matt Bellamy's guitar.
However, the Kaoss Pad has now become a symbol for spoilt rich kids who got a guitar for christmas and "want to sound like Muse". Some even spend vast amount of money actually installing the pad into their guitar at a custom guitar shop.
Later, they realise that it's use as a musical instrument is in fact incredibly limited and will discard it after several days of fiddling with "that Supermassive Black Hole noise" the pad can make.
Friend- But surely you want to learn guitar properly first and then build your own original guitar sound and style before spending £200 on a piece of shoddily made metal.
Spoilt rich kid- NOOOOOOOO! MUUUUUUUUUUUUSE! *growls* supermassive black hoooooooooooooooole!
