Well it isn't the tremolo/vibrato (at least the tube oscillator type) circuit. Here's a copy of Leo's application for the patent. Nver knew his first name was Clarence. :)

And it's not the PI section. As my 1948 Champion 600's label has the same patent warning.

I believe the Western Electric and AT&T patents covered some of the RC-based tone circuits and the NFL that Leo incorporated into his designs.

He actually formed an R&D company after selling Fender which bore his initials "CLF Research" (Clarence Leonidas Fender). I think he developed the micro-tilt neck and the bullet truss-rod adjustment system during this era.

You know, it maybe something as simple as the patent on vacuum tubes...

"Dr. Lee DeForest had just the plan of attack for Western Electric. In 1912, DeForest, "the father of radio" and owner of DeForest Radio Telephone Company, developed the audion, a three-element vacuum tube that could not only send radio waves more effectively, but amplify them as well.



Western Electric's Dr. Harold Arnold, who possessed the expertise in electron physics DeForest lacked, quickly grasped scientifically how the audion worked. The result was development of a high-vacuum tube for amplifying sound in telephone cables in April 1913. AT&T quickly purchased the audion patent from DeForest — allowing Western Electric to span the continent in 1914.


The technological breakthrough of the vacuum tube exerted a wide-ranging impact, revolutionizing communications. It would eventually lead to the creation of new industries, including radio, television, and sound motion pictures."

Rebel, very nice link. Dang, that Tone Lizard site is pretty cool. Now, I kinda remember that RCA had something to do with it. As they had shares in AT&T and WE, after WW2.

Never knew he had only one eye. Always see photos of him with two clear lens glasses. Learn something new everyday! :D


Thanks!

The Tone Lizard site is cool with a lot of info,whoever the guy is he believes in doing things the old way and doesn't agree with many of the new "tube amp gurus"...he uses oscilloscopes and old tube voltage meters and is very knowledgable,he learned the way old tube radio/tv repairmen approached their repairs.
