Quad w/ Impulses

[JMMP]

Here is a tone from my quad. I used a line out from the effects loop into GarageBand and used LA Convolver for an impulse of a 2:90 with a traditional 412 cab(I think)

Can anyone point me in the direction of some mark V tones that are similar to this? Can a MV get this clear?
