Mario, thanks for the reply. Amplitube 1 LE works very well, so I think you'll enjoy this one. Since I have Guitar Rig and recently bought a Behringer Bass V-Amp Pro off of Craigslist, I'm probably all set.

For those wanting a legitimate amp simulation without a great deal of hassle with too many controls - make sure to give Amplitube a spin. It's very light on computer resources; different than some of the good freeware amp simulations.
