Interesting point that Gibson is making now,
But in the begining it was something like this....
From the book Gibson Guitars - Ted McCarty's Golden Era, page 79
"Wood was one important consideration for the solidbody. The team tested different kinds and Allers worked with patternmakers on different types of bodies using different woods, An all-maple body had great sustain, but was deemed too heavy. An all-mahogany body didn't have enough sustain. So they tested various combinations to see how long a string would vibrate on a test fixture. McCarty described the test as simply attaching a string to two mounts on the body, plucking it, and measuring how long it would vibrate, In some cases, the string would vibrate for too long a period, and others for too short a period. Eventually, they found a suitable combination."
And all of this because it was quoted by Ted McCarty Page 74 "We got involved in the Les Paul solidbody because Leo copied one of Paul Bigsby's guitars. And as soon as we heard he had a solid body going on the market, I bought one from the company and we studied it. We had never made a solidbody - and he bolted the neck to the body, which was infamy as far as we were concerned. So we decided, about 1951, that we weren't going to let him have the whole market. So we decided to make a soldibody"
Interesting history, maybe Gibson should have explained it, how it actually was.
