Well, I tried something...
Just listen...
I like how you have given this a nice warm vintage mono sound
.
No tape saturation, but I used iZotope Vinyl for the distortion.
Lots of EQ-ing, cut off everything above 5kHz, tried to make it sound like if it was recorded with one mic directly to vinyl in 1920.
Nothin' wrong with a good ole lo-fi approach.
I took an interest in Old Time Radio a while back and picked up some recordings of things like Command Performance. This sounds not unlike those but still somewhat better quality.
