Sonic Emitter (weapon)

The sonic emitter is a weapon that appears in the Fallout: New Vegas add-on Old World Blues. It is a pistol-grip energy weapon developed at the Big Mountain Research and Development Center. It has five distinct models, each with different characteristics.

Characteristics
All variants are improved holdout weapons and are affected by the Professional perk. They can be repaired with any other variant of the Sonic Emitter, and any energy pistol with the Jury Rigging perk.

Creation
The player will receive a Sonic emitter - revelation at the conclusion of the quest Welcome to the Big Empty. Once Blind Diode Jefferson has been activated in The Sink, he can be given holotapes recovered throughout the facility to upgrade the Sonic Emitter. He can then play back the frequency necessary to reprogram any model of the sonic emitter to any other model. After the conclusion of the quest Sonic Emitter Upgrade, Jefferson can upgrade the Sonic Emitter to disable the Big MT Facility's many force-fields.
