I was just engaged in a conversation with a person on a YouTube comment thread who insisted that Les Paul designed the Gibson SG. He defended this opinion so fiercely that I tried to do some research. According to Wikipedia, when sales of the original Les Paul fell off in 1960, Gibson redesigned the Les Paul into what is now the SG. And did so without informing Les or any of his input. In a "Guitar World" web article "The History of the Gibson SG", by Mark Brakes, 3/27/20, they state, Older Gibson employees credit Larry Allers a wood carver and design engineer with the SG design. As SG enthusiast, most of us know Les refused to endorse the SG design and took his name off of it. I would be interested in seeing any further information about "Who designed the Gibson SG."
