With all due respect to the guys who think things are too bright, I think that alot of guys just don't realize how bright and edgy alot of what we consider "classic" tones really are. I GO for bright tones because you need that high end, IMO, to cut through a band and a mix. EVH, Pete Townsend, alot of Page, the tones are BRIGHT brash and snotty. Not really that pleasant to listen to on their own but in a mix they are just right.
I learned this when I put an Ecstacy blue channel up against a 67 plexi in the studio. I finally got what all the fuss was about- the plexi was like a wild horse, bordering on out of control- whereas the Bogner, while a nice sounding amp and fun to play through, coming out of a Bogner 2-12" sounded "like an already recorded guitar tone, coming out of studio monitors".
If it's too pretty, it ain't going to move you and cut through like the classic tones we all know and love did.
Anyways, these are stock speaker sims as well- in my Axe Ultra, I have Red Wirez greenback/57 on cap edge sims loaded, and those sound even brighter than the stock speaker sims. And I use em! Because they sound really real. You can take my word for it or not, but I sit in front of studio monitors all day listening to a greenback mic'd with a 57 through API's- I know what it sounds like. The Red Wirez are really close. For some reason, this tester Axe 2 I borrowed didn't have any Red Wirez IR's loaded (I think the production Axe 2 is supposed to come stock with a bunch of Red Wirez IR's).
