Keep in mind that the V4b still needs a speaker load, like any other tube amp, or you will damage the output transformer.Haha, didn't want to say it (*type it) out loud here.........but yeah, I was gona try it anyway just to see how it sounds. I was also considering using my GKMB800 as the power amp. So I'll try each out to see how it shakes out.
Thanks again DW. e.
Here's what I would do: Use a speaker level DI like a countryman off the parallel jack of the V4B's speaker cab. Run it to a little line mixer for level control, then into the effects return / power amp in of the auxiliary amp which has its own speaker cab.
