I love the sound of the V30s in the Tremoverbs.
I do, however, love the bottom end and punch of the Marshall's 75s.
Here is the rub.
The Tremoverbs are semi-open back so there really isn't any punch or authority with the bottom end.
The Marshall has the 75s in it and I am not a fan of them.
If you look at the pic you will see that the combos are on stands and the Marshall has the wheels removed and is sitting on the floor.
This is intentional, as I get the sweet V30s in my face and the bottom end from the Marshall below my belt, although the frequencies from the Marshall that I don't like can still be heard depending on where you stand, so I am not convinced that by it's placement below my belt, that I can state that it is sweeping below me and therefore non existent except for non-directional lower frequencies (if it even matters).
It is all relevant, as we all like different flavors of ice cream, so I don't want to put it down, it's just that I would be happier with all V30s.
If you like the 75s then I can say that they crush with this setup.
They are bone crushing.
Back in the 90s I had two of these cabs and a rig that was all digital.
I had 800 digital super clean, and I mean clean, watts of power 400/400.
I had a digital preamp and effects processor.
My band played covers like Whitesnake when Vai played with them etc. and this rig was amazing.
What was missing with that rig was tubes...tubes...tubes.
I would never go back.
First of all, everything was mic'd. Stage volumes were low.
The few times I turned it up LOUD it kinda sounded thin I guess, but whatever, that was then and this is now.
I will say that when I turn up my two Tremoverbs to half the volume of the other rig when I played it LOUD my ears would bleed.
No comparison.
