From your description, it appears that your guitar was fitted with an incorrect saddle. This is a mistake, and mistakes happen. Sometimes product configuration issues are created by the manufacturer and sometimes by their retail distributors. Either way, Gibson owns the mistake. We expect dealers to catch mistakes and remedy them before passing guitars into our hands. Sometimes this works and sometimes not. I have owned more than one Gibson acoustic, and I can vouch for their customer service: Gibson follows through to satisfy any reasonable customer complaint. The Gibson lifetime warranty is a valuable component of the purchase price.
