Thanks for the pics, Raz! I got a serious 80's flashback looking at a white Steinie backed by Hartke aluminum cones! That is a classic setup (original Steinberger owners would quibble) and it had to sound great, indeed.
Really glad to hear that the XT performed well for you and you liked the sound. None of us here had any doubt that you would.
That is a serious amount of gear on stage! Did you use all of it over the course of the gig? My back is aching looking at the cabs and heads, but at the same time I'm rather envious..
Yo Michael! Right now only the top two 410's are powered by the Mesa. And I have plenty of help moving the stuff around, when required. I'm wore out this morning, but not because we packed everything up last night (which we did

) but Saturday night I might have jumped around a little too much (although much less than normal) and I'm still feeling it. Need to get back into my diet and workout routine, but that's a different thread.
During our last show (and most prior ones) I was powering the fridge at the bottom with the Mesa and using the power amp for all the Hartke cabs. I wear earplugs - mainly because I'm right next to a lot of cymbals - and we set our stage volume to match "Woodchuck". Despite having my full stack powered, I couldn't hear it that well because I had the volume down so low, even though the overall volume was loud. On the other side of the drums are two full guitar stacks. Not only was this hard to manage via FOH, the front row was bathed in either searing guitar or tons o' bass (why is that bad??) - so we needed to get a handle on things but still hear and feel ourselves, plus all of the stacks look cool...
Anyway, we thought we'd try plugging into only our top cabs and see how that worked for us - and it was perfect! The sound goes over the crowds heads (we're on an elevated stage) but it's right at ear-level for all of us; I get a nice, loud bass sound I can hear, and our singer can feel everything at the front of the stage (including guitars) without overpowering the house mix. It really worked out great.
That said, depending on our set-up for an outdoors show, I'd power it all and crank it up. The power amp is driven from the Mesa's DI because it's much too hot for a sound board (I run out of the slave and into a DI box, with the slave level set to 1.5) but it captures all the nuances of the power tubes, including saturation - it's incredible! I don't get to experience that often enough.
The little Fender on the left is my personal amp - I was trying it through some of the speakers during our practice/set-up earlier in the week, but it made a nice stand for our set list and my phone so I left it there during the show.
I tuned the Spirit to drop-D and used it on three songs; the rest I played with the six string on the right. That bass is a real sleeper - see the Douglas 6 link in my sig - it sound and plays like something worth ten times as much.
