The mechanism, which allowed for easy string height adjustment without having to file down the \u003cbr\u003esaddles, must have been innovative even at the time.\u003cbr\u003eFrom the invention of the adjustable truss rod onward, Gibson has periodically created such historic legacies.\u003cbr\u003eIt is deeply moving to consider that this innovation not only allowed for easier adjustment but also had a significant impact on the sound—a sound that is integral to the music of artists like Donovan and Takuro Yoshida.\u003cbr\u003eSince this particular instrument uses replacement parts, it conforms to the specifications of the 1960s.\u003c\/p\u003e \u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0608\/1321\/3933\/files\/th_IMG_1628_b19ebe29-1dc7-44bc-94af-50f5fbc7e6ab.jpg?v=1752916763\"\u003e\u003c\/p\u003e \u003cp\u003eAnother distinctive feature of this particular guitar is its finish. The sunburst on the top of the body has faded and aged over time, resulting in a finish that closely resembles a honey sunburst. This is a characteristic finish often seen around 1960.\u003c\/p\u003e \u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0608\/1321\/3933\/files\/th_IMG_1671_11b54f7c-1c8d-4058-9e60-55854e4fdb4d.jpg?v=1752916794\"\u003e\u003c\/p\u003e \u003cp\u003e\u003cbr\u003eWhile this would seem to contradict the “FON” designation, the key here is the “2” stamped on the back of the headstock.
