Sorry to say but there is absolutely no relationship between that GAD41584 number and year 2009 that you can use in a serial number list. You actually don't need a serial number list for GADs! It's all printed inside the GAD! The real manufacturing date is actually coded in the manufacturing number that is internally stamped on the base of the heel block! So you need to use a lamp and a mirror most probably.
FMIC's hotline just doesn't know that...We actually discussed this quite a few times here already.
The GAD manufacturing info is not on the label (that's just a factory number) but on the neck block inside the body!
All GAD instruments are stamped with a 10 digit internal manufacturing number located inside at the base of the heel block. This number embodies production information about the instrument.
As an example, we’ll use a random number 1104330026.
The first two digits of this number identify the production year. In this case, 11 would stand for 2011.
The second two digits identify the production month. In this case, 04 would stand for April.
The next two digits, 33, are of no significance and are an internal number used by the vendor to identify their order number.
The last four digits identify the unit number of the order. In this case, 26 would stand for the 26th instrument made to the 33rd order.
Let us know what the number in your guitar is, so we can cross check if the info is correct. If your guitar is from May 2009 the 10 digit number should start with 0905xxxxxx.
