Fastrack Usb Only Gives Me "clean" Guitar?? Options

[strangedogs]

Bought a fastrack - didn't come with software but I use Garageband, Guitar Rig, Amplitube, etc... I was plugging directly in with an 1/8" adapter into my input on my G4 - sounds sweet. Now with the Fastrack (I've checked all settings in "SOUND" and "MIDI") I get only clean guitar from all apps? Tried plugging into my speakers and headphones tried different settings but all I get is "clean" - what am I doing wrong?

Clean is nice but I like down and dirty too

NO crunch at all - no matter how I set it up or how I turn the knobs - without it I get the Marshall sound - with it - sounds like a clean clean guitar - no crunch in Guitar Rig software or Amplitube - no crunch in GB either - disconnected it and set back up with built-in inputs and outputs - I have crunch?? is it broken or am I a dummy?
