Ooh-ee! Yeah, dig that sweet music! Damn, it's good to be back on-line!

Blind Diode Jefferson is a jukebox fixed with an artificial personality in the Big MT in 2281.


A workstation created by Dr Mobius for prototyping sonic weapon designs,[1][2] Blind Diode was rendered mute when the scientist removed all music drives from it to create more space for acoustical processors.[3] Its artificial personality was coded after a laid-back blues musician - perfectly content with its lot in life.[4] Notably, it contains backup schematics for sonic emitters.[5]

Its personality drive was removed when Dr Mobius broke ties with the Think Tank, later removed to Higgs Village's House #108.

Notable quotes

  • "And then you got to figure that the noes and the don'ts of life are just there to make you stronger. And the satisfied man is an ignorant man, and then one day you'll realize that facts are stubborn things and it doesn't stop 'til the fat lady sings. And if a woman is skinny, don't trust her. It means that she don't eat much, and woman that don't eat can't cook. And if she can't cook, she don't read a book. And that's no situation to be in. One more thing, young man. A happy wife is a happy life. It's better to sleep on the edge of the roof than to live in a house with a quarrelsome woman."
  • "I ever tell you about Saxomotron version 4.0? That cat was the best trumpet player I ever met."
  • "Here and now got its ups and downs, but... focusing on the past like it was way better? That's just Old World Blues..."
  • "You heard of Doc Boney? Sang with the staff band till his wife caught him in bed with a nurse. Now he haunts the Med Center, still singing the blues."
  • "Some day, I'd like to meet the man who's got no blues to sing."
  • "You ever heard of Tiny Lester Lutton? Best jazzy harmonica I ever heard. Mind you, being a super mutant with no lips... don't ask me how he played."
  • "Ooh-ee! Yeah, dig that sweet music! Damn, it's good to be back on-line!"
  • "Look who's back to kick off the dust. Hope you ain't still singing them Old World Blues."
  • "What's the haps?"
  • "So you beat the big brains at their own game, huh? Guess you'll be putting your walking shoes on again, hitting that old lonesome road."

Behind the scenes


  • Jefferson's script doesn't account for the sonic emitter in the player's possession, allowing for multiple copies of the weapon to be obtained just by asking for the same type to dispensed over and over again.


Blind Diode Jefferson appears only in the Fallout: New Vegas add-on Old World Blues.


  1. The Courier: "I found a soundwave file for you."
    Blind Diode Jefferson: "Right on, daddy-o/baby! Just plug it in and I'll mix you up a sweet, sweet sound."
    (Blind Diode Jefferson's dialogue)
  2. The Courier: "What's your purpose here?"
    Blind Diode Jefferson: "Dig, I'm-a acoustical wizard, kid. Ol' Doc Mo used me to prototype his sonic weapon designs. Get me a good sample base to work from and I can whip up a wave that makes Jericho look like a kazoo."
    (Blind Diode Jefferson's dialogue)
  3. The Courier: "Do you play music?"
    Blind Diode Jefferson: "Mmm... Used to, long time ago. Then Ol' Doc Mo ripped out my music drives and stuck in more acoustical processors. Guess you could say I got the blues, even if I can't play them no more."
    (Blind Diode Jefferson's dialogue)
  4. The Courier: "You seem pretty laid-back for an engine of destruction."
    Blind Diode Jefferson: "Why not? Ain't like I got nothing to prove. Not like that Toaster - now that boy got some issues."
    (Blind Diode Jefferson's dialogue)
  5. The Courier: "I lost my Sonic Emitter. Can you make me a new one?"
    Blind Diode Jefferson: "That's a shame, chief! Nobody oughta go through life without music on hand. Just head over to smarty-puck in the main room and he'll sell you one."
