Not sure on the date. This one has been played and loved. Lightly reliced with nicks around the edges, but overall in good condition. Doesn't have the mystery chip, but will come with the second stock chip (TL072ACP), and my favorite, NE5532P. Blue LED and signed back plate. Sounds much better then the limited run PCB EB I had. Does not come with the original box or paperwork, but will be packed carefully. $old Paypal/shipped.
