That's a horrible experience; sorry you had to go through that
I have a km6 mkii and think the KM is actually more like the Majesty than unlike: compensated nut, volume control out of the way, neck through construction, HH configuration, active electronics
The USA Custom Shop Mkiii’s come in a couple versions. Only the studio version has a neck thru on it, mine is the bolt on. They’re identical other than two things, the aforementioned difference and the studio comes with a rechargeable battery port for the Fishman active pickups.
Then there is the import version. The Diamond Series imports are still a good instrument but not even close to being in the same league as the USA Custom Shop ones.
Having owned both I can say for a fact that the Majesty 7 and Schecter USA Custom Shop Mk7 feel nothing alike. They both feel amazing to play, equally amazing actually I would say even BUT they do not feel even remotely close to like each other because of the shape of the necks being so drastically different. Also the Majesty is a glossed painted neck and whereas EBMM makes the best glossed painted necks anyone ever made it still can get somewhat tacky and even when it’s not is not the same as the wood on the Custom Shop Schecter.
Both have humbucking pickups but the Majesty has passives and the Schecter comes stock with actives.
The Majesty comes in Mahogany/Maple top or Alder/Maple top. The Schecter is Swamp Ash/Burl Maple top.
The Majesty has a Mahogany neck and the Schecter has a 9 piece Wenge/Purple Heart/Maple neck.
The Majesty has coil splitting push/pull, volume boost push/pull and Piezo. The Schecter has different selectable modes/voices for the Fishman Fluence pickups but not anything in common with the Illuminators, especially the tone not even same ballpark.
The Majesty has the more traditional style locking tuners and the Schecter has open gear hipshot tuners which aren’t in the same shape as normal tuners at all.
The Majesty has a floating bridge with piezo pickups built in and the Schecter has a plain hipshot bridge.
I could actually go on with more differences I’m sure but I won’t.
Also if you’re saying an import is anywhere near the league of an EBMM or Schecter Custom Shop guitar you’re wrong (I’m not sure if your Mkii is Diamond Series import or USA Custom Shop, nothing wrong with the import KM guitars they’re nice for imports much like the EB’s Sterling line).
I am still a huge EBMM fan including JP’s guitars in general and their others as well I always have been just to be clear to all, I just wasn’t happy with the Majesty for the reasons I spoke of so I decided to go a completely different direction. The two feel and sound completely unlike each other in pretty much every way but both are top of the line quality made instruments (except the garbage electronics they’re sticking in Majesty’s in my opinion and honestly I want a fan of the Fishman Fluence in the KM either so I went with passive pickups instead and I like it much better but that’s beside the point) and even both of their imports are nice for imports.
