Very welcome!
Also, if I recall correctly you seem to be drawn to Mesa type IR's, and thus one would assume more mid to high gain tones with V30's. The "M-SB-75" actually pairs wonderfully with the V30-EN speakers to add low mid girth without being dead sounding (as the M75 also has some bite on top of those low mids) like many others with big low mids tend to be. This pairing is pillowy, full, and characterful. In addition to seedoftheday's post earlier here that shows the M75, justinjcm900 also just posted a clip recently of the M75 IR's. In this one they're on their own I believe, but you may be able to hear what I'm referring to:
The V30/M75 pairing is something I had many customers mention not only with the Studio Mix Marshall cab, but even this past week I have spoken with multiple in private conversation who have done this and loved it.
