And I can see that the sound of a Mark 5 may not be for you. They have a unique thing and don't sound like anything else; instead of that ripsaw kind of sound that, say a Recto or a lot of Marshalls have, they have a more liquid, singing kind of gain that may not be what you or someone else is looking for. Was just commenting though that the amount of gain they have on tap is pretty absurd. I've not run across many amps that can compete with a Mark 5 for the sheee amount of gain, but of course the nature of that gain can be quite different.
That's exactly what I was told by many about the Mark 5. But, I'm convinced that "plenty of gain" for some people, is akin to Malcolm Young's tone.
But, you are right, it's a gain structure thing. I've that chain saw mid range coupled with enough low end to get speaker movement.
I really tried to like the Mesa tone...
