Ok today i bought an Ibanez EXB445 (for a 100 bucks) and the serial is C306995.
it's an oddball serial as there usually letter+7 or 8 digits, but mines only 6.

I know the C is cort and the bass is made in korea
any help would be appreciated.

Actually if im reading it right which im probably not.
995=production number
Lots of conflicting info concerning the EXB445. Some sources are saying 1996, others saying earlier. Found a 1992 catalogue, so 1993 is looking much more likely now.

Although it'd be really nice if they kept a bit more consistant with their serial numbering and add a 9 or a 0 before that 3.
