One more thing... I see from the above mentioned book that the LG-0 featured a mahogany top, which would emphasize more of the mid-tones. It also had ladder bracing, like the LG-1, rather than the X-bracing that the LG-2 and LG-3 had. The LG-0 also had, until the mid-60s, a spruce bridge pad which, though it worked well tonally with the mahogany top, would wear out more quickly from the pressure of the ball-ends of the strings. Gibson later started making them with mahogany. But from 1962 to 1966, Gibson was putting a "special" black plastic bridge on them which was held on by 4 bolts and flat washers from the inside. It was mainly intended to simplify repairs but caused so many other problems (cracking, less stability) it was abandoned in `66 for a rosewood bridge with an adjustable saddle.
