I’m going to wander off from the truckin’ theme of the thread again, but I think this is where this will be appreciated. I recently found some of the earliest uses of the sonovox (or talk box).
@Megaterio Llamas have you heard of Alvino Rey or Pete Drake? (I’m guessing you have, you’re a tough one to stump with my discoveries

).
@Yossarian i think you may like this as well.
As far back as 1939, Alvino Rey was the first person known to modulate musical sounds using a voice. He would use a pilot-style carbon throat mic and run it through the amplifier for his pedal steel. His wife would sometimes help with the voice part while he played, and the result would be making his pedal steel sound like it was “talking/singing”.
A later variation of the throat mic became known as the “sonovox”. This was also used to create talking cartoony effects in several movies in the 40s, Dumbo being one of them.
In the 60s, Pete Drake, who was also a pedal steel player, modified the device by using a speaker in a separate box and a length of surgical tubing to run the sound into his mouth.
In the 70s a high powered talk box was made. Since then performers like joe Walsh and Peter Frampton have used them in concert and on records.
That’s the brief history....I’m off to YouTube to gather some videos for y’all.
