aiwass, not only are the people at the Line6 factory trippin about the presets they are also schitzo about how they give them to you. See you have banks and each bank has 4 sounds. You can only use one bank at a time so logically its set up something like this:

1:clean
2:clean boost
3:dirty
4:dirty lead

alright makes since but its sent to you with pre set banks like:

1:death metal distortion
2:somehting with an near infinite repeting delay
3:some other random guitar sound
4:jazz chorus

its like they were pulled out of a hat or something
