Scott from Electro-Harmonix doesn't just blog about their newer FX boxes. He also digs up videos of old products that EHX no longer makes like the "Golden Throat" talk box, a box that sounds like a vocoder, but wasn't, as it "physically pumped audio (not an electric signanl) up a tube, into the player's mouth, to then be shaped and captured via an external microphone."
Bad ass. (Several versions were released.)
Roger Troutman's group Zapp famously used a Golden Throat for the lead vocal line of "California Love", which was remade in 1995 by 2Pac and Dr. Dre with Troutman rerecording the vocals. "California Love" was itself a remake of sorts, with the foundation lick being lifted whole cloth from Joe Cocker's 1972 track "Woman to Woman". [Sample below.]
In the above video, a cornball French dude named "Mo' Cheeze" puts the Golden Throat off to hilariously right-on effect. (Fun experiment: Close your eyes, pretend you're listening to a track from the early '90s, then open your eyes to gaze on the smooze leer of Mssr. Cheeze.)
