It looks like a 20th Anniversary 20th5 model. If so, they were limited to only 350 made, came with a 20th Anniversary hardshell case and 20th Anniversary leather strap as well as letter of authenticity and what number in the series your bass is. If need be, you can call Ibanez customer service and give them the serial number and they can give you all of the info needed on the bass.
