Well, I was in the exact situation once, and you can see what I did on my website:

Go to Music, The Arsenal, then "Secret Cabinet". This worked suitably well, and was silent. I will say that I got a much more dynamic and playable tone this way than through speaker simulation. It was very similar to being in a control room with your amp cranked up in an Iso booth or something. The guitar tones on "Watching You Fall" in the Jukebox here were recorded that way if you want an idea of what to expect.
(Yeah, I'm a geek

My 2 cents...
