Marshall is up there with the likes of Gibby and others for being blatant marketers 100% of the way... I'm not saying it's a BAD thing, I'm just saying I don't "do" siggy models (EXCEPT FOR
LES PAULS AND LETS JUST SAY THAT'S A GIVEN ALRIGHT

).
Whatever, the psychology behind marketing - and we all know this - is offering something that makes us think we might garner something that gives us that extra level, the inspiration, the magical ability to play like [enter signature model rockstar person's name here]. C'mon, that's what it's ALL about!?!?!?! I haven't read much
AT ALL on this forum about Yngwie's "tone". I've heard a LOT of peeps talk about his abilities - and damn I'm 100% DOWN with that - that cat's off the hook, period. Incredible guitarist. He's a bloody master. No denying it. But I haven't heard or read much about the interest in his "tone". Tool fans, there's many of us here, a lot of us own - taaaaadaaaa - Diezel VH4s. Slash fans, taaaaaadaaaaaa - the AFD and Plexi proper. Who likes LOG, betcha you like Mesas too. It's all there, and there's nothing wrong with it. But the fact is I'm wondering if Marshall took an odd turn here(?) because, of the stuff they've schlepped out in the siggy department, much of it has been tone based marketing. Yngwie's got less of a signature "tone" than he does a signature "style", and that's something I don't think anyone here can replicate.
Just my take on things. Since it's not 'tone' they're trying to convey with the YJM model, it's Yngwie himself they're trying to schlepp out. And since they're a bright enough bunch to know that those who buy will soon find out they're not any closer to playing like the master himself, they (Marshall) put a bunch of fiddlywink additions into the amp so it takes the prospective buyer longer to [try and] find that magic 'crystal lattice' in the amp, but at the end of the day, you're still you playing an amp. And you ain't Yngwie.
