just the cab sounds,
not any sims or modelers......

thinking about diving in.

Been doing that using both an Axe-FX and a Helix.
IMO, It's particularly cool when you create your own Cab IRs.
Cabs you like... mic'd the way you like

celestion has release a library of their own product, in a plethora of cabs,
i've listened to all the samples, and like several.
 
i would probably get a couple here, there, and make a few of my own.
 
i already have a weber mass lite i could use as the line out,
rme babyface pro for an interface,
should be pretty simple, eh?
 
i'm thinking of using MixIR convolution plug-in,
i understand it plays the entire 500ms sample at many sample rates
 

Try Torpedo Wall of Sound 4. It can load 3rd party IRs as well.

If you've a "real amp" consider trying a Palmer or Mesa speaker emulator/load box. Not cheap, but they sound fine and no cpu hit or latency issues at all.

ok, let me quantify....
 
i have a '82 mesa boogie mark IIb 60 watt head,
and a plethora of cabinets.
 
i currently run the boogie thru a weber mass lite, at various levels of attenuation, to match the overdrive i pull out of the amp, with the volume in the studio.
 
i also have a Palmer PDI-09 that i use as a cab filter and direct box, when i want to go straight from head to interface.
this is currently my favorite way to collect my tracks on guitar.
 
i can mic cabs, and use the palmer at the same time, and combine tracks, which is the typical way i mix my guitar tracks.
 
i've used modelers before, and do not like them, for a variety of reasons i won't go into right now.
 
 
as the IR and convolution technology has progressed, i now see that this may be another level of capture that is worthwhile,
so i'm curious to see who is using it, and who has a/b'd it against units like the palmer or radial JDX, and live micing of cabinets.
 
 
i know that pros like pete thorn and scott henderson swear by them now,
and those guys came from very pure tube amp/miced cabs backgrounds.
 
 current rig layout:

 
cabs available:
demeter iso cab with eminence legend 112, roland closed back 1x12 with an old celestion G12C-30, roland open back 1x12 cab with a celestion heritage G12h-55, Avatar vintage closed back 1x12  with a celestion british greenback.

here's an example of my current recording sounds (guitars)....
this features miced up guitars in the first section,
direct by palmer guitars on the 2nd section

And those maracas.

those maracas are not impulse responses....
they are purely impulse.
 

And yellow.
