zeppe1983 0 Report post Posted February 28, 2013 Hi, my name is Stefano and i have a Gibson Es 175 with this serial number : 81308501. Yesterday i was reading that the gibson until 1989 changed the outer laminates from maple to mahogany. I know that this change was not well received and in the 1991 the maple was reintroduced. I want know if these dates (1989-1991) are correct and if my outer laminate's guitar is maple or mahogany. Thanks a lot. All the best. Quote Share this post Link to post Share on other sites
