Linearizer style circuits

In the world of high power RF, and there is a common technique of using a "linearizer" to make a vacuum tube more.... linear. It seems like doing it wrong and putting it in a pedal could be a cool thing, though I am guessing at audio frequencies there might be some challenges. You should be able to shape the transfer curve and tune the harmonic content to a decent extent if it works though.

Anyone ever seen something like this done in guitars? I can do some more research on actual circuits next week, but figured I would start off by asking the stupid question first. Here is one from a patent as a start

I'm not knowledgeable enough to discuss either in any depth, but that looks awfully similar to the diode ring compressor used in the Ethos TWE-1 (and a couple others).

As always, you're very observant. I had glanced at the schematic before, but stupidly didn't recognize the bridge-like configuration as it's not drawn in the conventional "diamond" way - duh...

Thanks for posting that circuit! It's in the queue now. Hopefully I can find some time next week to simulate some of them and do some more research. I am really curious how something with significant gain expansion that goes into hard clipping would sound. Probably terrible.

Cool patent, it's from Varian Associates for use w/ a klystron...
That woke up some old neurons that haven't been touched in ~40 yrs...

Sorry for the pedantry but it's really for use with a TWT. Both are linear beam vacuum electronics, but pretty different circuit structures. Varian are the kylstron OGs, but dont really make these sorts of devices any longer.
