Well....An update:
I should maybe add that the SVT-212AV cab got a tweeter, so the NUX IR I use of it doesn't start to roll off high end steeply before around 7/8 or so kHz.
So essentially this is still a bi-amping sort of setup, mind an old fashioned kind, with no crossover as such, though I do have HPF engaged in the parametric EQ between the Orange guitar amp and cab, the cab doing it's part as well.
As well as the Joyo Oxford Sound, earlier in the chain, mixed with direct/"clean" signal, got a simple analog cab filter build in, that also rolls off some low end.
Very punchy and snappy tone, with a lot of zing, which of course partly is also thanks to the fact that I use the bridge J pickup of my bass soloed, as well as the bass it self inherently got a very growly clear character.
And by the way, the drives on this unit sounds great, albeit you can still hear that they are digital, there is just something too clean/hi-fi and predictable about them to be analog drives, now this isn't necessarily a bad thing, as said they do sound great, but personally I wouldn't use them without being blended or stacked with analog drive pedals.
I packed away the Boss GT-1000CORE to be sold soon again, and I am back at using my old complicated single pedal setup, with analog parallel paths (signal path is listed on my forum profile if anyone's interested).
It just didn't feel right in my fingers, and I struggled to make it sound just right.
At least now I tried it, and know now that multi effects as the central piece in my setup is not for me.
If any the Boss ought to have been it with its flexible signal routing possibilities.
It just didn't quite work out as I had hoped for.
Back at using my old trusty lowly Zoom B1Xon (with hacked firmware for extra effects) for mainly reverb and additional reverb effects, and the odd wildcard effect occasionally.
And I am actually happy with that.
And honestly I like the basic always on reverb I programmed on the Zoom (a subtle dark plate reverb with some pre-delay going into a subtle spring reverb) slightly better than what I could cope from the Boss single reverb options (for one the spring reverb on the Zoom actually behave somewhat like a real spring reverb, unlike that on the Boss).
