5. Roland SP-404SX
The SP-404 is one of the most ubiquitous samplers out there. Everyone from DJs to experimental electronic artists use them. Not only can you play back your classic vocal samples, but you can also record, edit and sample any audio, even playing it like a keyboard. You can also add effects to any sample, including a microphone running into it. As a matter of fact, back in the day, experimental indie pioneers Animal Collective had a live setup that pretty much consisted of five or six of these and a guitar.
