The Faderator

The Faderator is a debug weapon in the Fallout: New Vegas expansions Dead Money, Honest Hearts, Old World Blues, Lonesome Road, and Gun Runners' Arsenal.

Characteristics
The Faderator is a unique variant of the Gauss rifle, which in appearance is identical to the standard weapon. Its actual properties are considerably different, with the following distinctions: a lower ammunition usage per shot, larger ammunition capacity, automatic operation, very high hit chance in V.A.T.S., tons of knockback, and a dramatically increased rate of fire, bringing the weapon's calculated damage-per-second to 20'160.

It shoots a spread of 3 shots with one trigger pull, similar to a shotgun. In V.A.T.S. it fires 12 shots, with 3 rounds per shot, bringing the total number of rounds fired to 36.

Based on these factors, as well as the weapon only appearing in one normally inaccessible test cell, it can be assumed that The Faderator was never meant for legitimate inclusion in the add-ons. Like the Debug 9mm and The Disintegrator laser rifle, it's likely that The Faderator was a weapon designed to help developers and playtesters get through combat as quickly as possible, which is further backed up by the low skill and Strength requirement for effective use.

Durability
The Faderator can fire a total of about 3995 shots using standard cells from full condition before breaking.

Locations
The Faderator cannot be found anywhere in the game, and can only be obtained through the use of console commands or use of game save modding tools. Also, it can be found in a room where the player can be transported to with console command.
