Ok, thanks for the clarification, that's what I suspected too.
So how come someone mentioned that the "slave out" is after the OT and can be used for direct recording?
In my experience from going from preamp to a pc recording interface, the biggest challenge you're facing isn't the lack of speaker cabinets but rather a lack of power amplification. My peavey rockmaster's direct signal sounds like a dry, fizzy, bee hive, but when I plug it through a tube amp's fx return all of a sudden it's punchy and warm, and not fizzy anymore.
I tried to find a good power amp sim that can add that magical filtering and power tube saturation to the preamp signal, but nothing even came close to what a real power amp does. The most promising thing I heard was Nebula 3, which supposedly is an impulse response plugin that changes the response dynamically based on a host of factors, but I didn't check that out as it costs money.
Simply using a cab impulse will help a lot, but I don't think it will get you a real tube sound.
However for brokeass musicians like me it'll have to suffice. I recommend guitarhack's IR collection, and Noirin's Diezel IR, I think you can google to find those.
There are probably other good ones out there, these are just the ones I happen to know about.
