I was having a look on Facebook Marketplace and came across this 2011 Fender American Standard Precision bass. I looked up the serial number but it doesn't check out on the Fender site? From what I can see, the serial is 10033110, but according to Fender records, I think it should have a US prefix before the numbers? The bass has been modified with a John East pre-amp and Lace Bass-Bar pickups, so it's not stock switches etc.
