You have one great guitar and as long as you didn't pay more than double what a standard KE2 is going for and the craftsmanship is on point ( the trem route is not crooked) I would not sweat the fact it was sold under the CS pretense and has a U prefix, it basically is a custom piece especially if that graphic is factory. That has been argued in length already and the debate will continue So lets go figure it out, Custom shop equals 2 plus years wait and $4000 and up in price and Custom select equals 4 - 6 months wait and $2500 - $3000 and they both have the J prefix. NOTES: Jackson JS, X and Pro Series guitars that were made from 2013 until present day feature a 10-digit alphanumeric serial number located on the back of the. So who knows the method to their madness, The true debate is over the Custom Shop vs the Custom Select Series and the fact that they both sport the J prefix. and chrome hardware ( i since swapped it to all black) and is not just a plain ole SL2H with a custom paint job. That is awesome, good buy for 170 Id say. With the serial number you can probably call the company for an estimate on the date.

What is even stranger is that I have a soloist that has custom shop on the headstock and U prefix (U20175) but it has custom features such as pearl white finish w/matching headstock, blank ebony fretboard, black binding on neck and headstock, EMGs with battery cavity on the back. You can probably find a serial number somewhere like under the neck joint, or on the back of the neck printed there.
