1 Elizabeth Hummel 1 year ago hi there. New to this site, as I was just gifted a Gretsch. When I tried to enter the information about the guitar, it did not give me the option of entering 1958. So I tried "unknown" but it would not let me proceed without choosing other options. I am going by the serial number, which your site indicated was from 1958 (27***). It also says Anniversary Model with a picture of a diamond on the headboard, which seems to be 1958. Please let me know how to proceed with finding out more about my guitar. Thanks!
