Gibson has a section in their site dedicated to the identification and meanings behind their serial numbering system.

So my serial number is 72657067.
YDDDYPPP

YY is the production year
DDD is the day of the year
PPP is the plant designation and/or instrument rank

YY = 72657067 : 77 = 1977
DDD = 72657067 : 265 =
PPP = 72657067 : 067 = 67th made on that day

Can anyone help me in figuring out what the DDD is the day of the year is because it is just baffling me to know end! I took this quote directly from the Gibson website and it’s hard to follow.

Thanx in advance!

Keep on Jammin’
