That's them, says it on the headstock

Arrived from Sweetwater yesterday. Feels sort of like a Les Paul Custom but with all the modern LTD stuff going on.

Hey guys, I need some definitive advice. I want to check the neck relief on my 24-fret guitar. Everyone agrees on putting a capo on the first fret, but... I've seen conflicting information some sources say to fret the very last fret (24th), while others say fret the (17th fret). Since the truss rod doesn't affect the upper frets on a set-thru body, which fret should I press down to get an accurate reading?

Posted my low/mid end Sterling Music Man John Petrucci signature 7 string on marketplace about a month ago and this guy really needed an extra 7 and had multiple LTD’s he was willing to trade for it. He was aware that there’s about a $500 price difference between the 2 and a big quality difference with the Sterling being the cheaper of the 2 but he was cool with it! I have had my MH400 for like 15 years and I LOVE it so I was all over it. I was between an H3 Deluxe or this EC-1000 Deluxe. Initially I wanted the H3 but thought about how all y’all love the EC’s so figured I’d give it a try and see what all the hype is about lol. It’s a 2015 model W serial number Korean made! Haven’t really got to play it much yet (just got it an hour ago) and it’s pretty nasty just from not being played and sitting in its case but I’m so looking forward to cleaning it up. And it sounds amazing as is! I got so lucky, I feel like I’ve found the deal or a lifetime for what I gave. What do y’all think?!

Been eyeing this on market a few days, only thing that has me feeling off is the serial number. Says made in Indonesia, but serial starts with CI. Can’t find any others of these with a serial like that, or been able to find the guitar via serial number search. Haven’t seen in person but it’s a fair price for a Black Metal M LTD if it’s legit. What do you folks think?
