Beastbox Preamp Identities

  • Entire Tube Architecture
    With four tube cascades Beastbox can run from a magnificent compressed clean to a stage-crushing Lead in a moment.
  • Authentic Tubes Voltage
    Don't be misled with low-voltage Beastbox power adapter. Internal voltage converter generates more than three hundred volts to reveal all tubes potential.
  • Lead / Crunch / Clean Channels
    With three channels and independent controls for Clean / Distorted sections, you can discover the desired voice to put into the mix.
  • IR Amp / Cab Simulation
    Beastbox has an outstanding guitar stack simulation based on Impulse Response technology. Load up to eight IRs into Flash memory to play with the feel of a real stack.
  • FX Loop
    Beastbox has a switchable FX loop and allows you to engage or disengage all post-preamp modulation devices connected to the FX Loop with one click.
  • HeadPhones
    We made a headphones output to let you practice with additional control on your technique. Connect your phone to AUX input and set up your backtrack.
    Headphones are IR cabsimmed.
  • Portable Design
    We spent a lot of time on putting impressive functionality into a small-sized device. As a result, Beastbox won't take up too much space in your bag or pedalboard.
  • Charming Lights
    Yes, we found beauty in this lighting. Anyway, you can turn it off to activate a stealth mode.
  • Hand Built
    We believe machines are good. However human beings are unbeatable. Handcrafting adds a certain feel to every assembled device. All of our creations have lots of human work.
