apparently I can't post the links but there are a bunch of tones in the patches section here:
instituteofnoise . com / L6 / filesearch . asp
including some U2 patches:
instituteofnoise . com / upload / fileaction . asp ?idPatchFile=1041
and
instituteofnoise . com / upload / fileaction . asp?idPatchFile=1130
The official Line 6 site is:
customtone . com / library . html ?product_id=12
hope this helps,
cheers
