The sonic emitter - Gabriel's bark is a weapon in the Fallout: New Vegas add-on Old World Blues.


The sonic emitter - Gabriel's bark is an Energy Weapons pistol with bonus damage against robots and power armor wearers, as well as a unique "critical strike knockback" effect, knocking enemies down on critical strikes. This sonic emitter is named after the cyberdog Gabriel, and the holodisk containing the upgrade is found in one of Gabriel's digging spots. This sonic emitter modulation has a burgundy oscilloscope.

As a one-handed Energy Weapon, the sonic emitter - Gabriel's bark is affected by The Professional perk, and counts as an improved holdout weapon.

The knockback effect, which is affected by Stonewall, will push targets away for a total of 15 game units.


The sonic emitter - Gabriel's bark can fire a total of about 495 times using standard cells, from full condition before breaking.

The holotape for the modification, Audio Sample - Gabriel's Bark, is located in X-8 research center's residential test facility, in a dig-hole spot of the cave area with Gabe.


  • As with all sonic emitter modulations, it is necessary to install the Blind Diode Jefferson's personality chip before this remodulation can be applied to the sonic emitter.
  • All cyberdogs are affected by the additional EMP damage done by this weapon.


  • PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 The knockback effect modifies the script used by bighorners in order to make it work with the sonic emitter. This modification completely nullifies the effect when it is used by bighorners. [verified]
  • Playstation 3Playstation 3 Sometimes, after entering the testing area and killing Gabe, leaving while the think tanks are still talking, then returning to the testing area and acquiring the Gabriel's Bark holotape, even though the holotape was picked it up, it is missing from inventory.

  • Xbox 360Xbox 360 In some playthroughs, Audio Sample - Gabriel's Bark will not spawn in any of the digging spots and there is no way to get the holotape to re-spawn through a previous reload or otherwise. [verified]
