For Serial Number formats, see this post in our G&L Knowledgebase forum:
Serial number significance.
Here is the section on Tribute Series serial number formats:
The G&L Tribute models have a different serial numbering scheme. All the Tribute Models have the build year and month coded in the serial number.
Tribute serial number formats are:
YYMXXXX or YMMXXXX (e.g., 0123456 - Made In Japan Tribute Models only)
YYMMXXXX (e.g., 01234567 - Made In Korea Tribute Models only)
YYMMXXXXX (e.g., 012345678 - Made In Indonesia Tribute Models only)
LYYMMXXXX (e.g., L01234567 - Made In China Tribute Models only)
LYYMMXXXXX (e.g., L012345678 - Made In China Tribute Models only)
Serial number location is on the back of the headstock.

You will see that your guitar has a Swamp Ash body with the Natural Gloss finish.
Hope this helps.
