I think you miss read what I wrote. I never said anything about amps or patches of some sort of modeler, that was your assumption. You also missed the italic "can", which means that there's a compromise on that path, or that it isn't entirely truth... I also stated that, for the sake of light traveling, one seven is better than 2 guitars and my last post says one should buy more guitars just for more guitars, it doesn't really matters what justification one may have, MORE GUITARS justifies every guitar bought, always. Peace out.
I absolutely didn't misread what you wrote. I disagree with what you wrote. Completely.
My response regarding amps was both an analogy and an extrapolation. It was apropos and crystal clear. If mindset doesn't matter, John Mayer should be able to write Slow Dancing with a Mayones 8 string through a Horizon Effects Precision Drive and Peavey Invective - and have it come out written exactly the same.
Music and gear are experiential and subjective. If you think split-coil 7 string pickups (CL, Illuminator?) or piezos sound like a Strat (quack, 2 and 4, chime, etc) or a Tele (twang) that's great for you. They don't sound in the same universe to me and many others. If 8 vs 7 vs 6 string doesn't matter, John Mayer should be able to play Slow Dancing with a Mayones 8 string through a Horizon Effects Precision Drive and Peavey Invective - and have it sound nearly the same.
There is no best for everyone, just for you. I'm not going to debate you any further on opinions.

OP, either are good choices like I said before. There are many guitars as good as a Majesty 7 for their different reasons, but I'd argue none better. I haven't played the GG Charvel, but I've played nearly every other model. I'm assuming since your prices had the weird British 'L' thingy, you're in Britain? Why not visit some local stores (Andertons?) and try them first? Maybe you'll love the Majesty but decide on a 6 instead? Or decide it plays different enough than your Jackson that you still want the 7. Maybe it will replace the Jackson and you can get a JP6 and a Majesty 7 lol. Who knows.
As always... YMMV.
