Zoom Sampletraks still go relatively cheap these days and they have a good gritty sound like the overpriced SP-1200 or MPCs. Also has a lovely "Resample" function which adds to the grit. The built in sequencer's pretty awful though ( despite the unusual and charismatic swing function) and it's not easy to mute other sounds while a pattern's looping so forgive the repetitious nature of this track. Very fun and quick to get out a quick beat of this little machine.
Samples from: Curious Alice (1971) (voice and synths), Bill Withers - Use Me Up (drums), John Baker - Caves of Steel (ride cymbal loop), FindSounds (bass note).
