Plug in the Full Circle to your upright bass and the sound of your rhythms will be even easier to hear in the mix. Whether it's big, fat and punchy pizz, full-voiced arco or slap, you'll hear all the acoustic qualities, dynamics and nuances of your bass��and so will your audience. A Platinum Stage or Platinum Pro EQ preamp (sold separately) which have dedicated Bass modes, are recommended, but not required.
