om, I have Amplitube and with it comes a version of Tonex and I know that you have a number of various fuzz, distortion, and overdrive pedal emulations in them. Each pedal emulation has controls so that you can change the tone and such. I believe that free versions have a couple of those pedal emulations: note that I have the paid version of Amplitube thus only speculating on what the free version has. I still think it may be worth it to you to DL them and give them a try.

Note I agree that many demos sound thin. I believe they are currently aiming their products at today's guitar sound (the thin and treble rectifier sound) and not the classic fuzz tones. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
