IL could really do with some guitar/speaker cabinet responses in the downloader or installer BTW, if anyone from IL happens to read this. Hardcore totally is not good. I'd almost go as far to say it's a waste of harddrive space and data bandwidth.
It's one and only redeeming feature for me is that it's the only way in a default installation, to have any cabinet emulation, without having to download 3rd party impulses.[/s]
Edit 2017: This is well out of date and from when there was only 5 cab responses.
