Actually I explaining what I wanted incorrectly. My 20th Shiva IS dark and saggy! Love it.
But the 20th is more open than the original Shiva. I have three cabs. One with V30s, one with high powered greenbacks and one with Lynchbacks.

I love my PWE, sound like the best Marshall I have ever played at any volume.

I think I want something simple and that can take 6L6 tubes and is less forgiving.
And, takes pedals well. I am thinking Mesa Boogie Electradyne.

Last night at practice my Shiva sounded dark and I had the presence and treble at 1:00 o'clock.
