No idea what the lad was using, but when I took the Mrs to a gig at Twickenham in 2008, one of the support bands was Biffy Clyro.
They were quite possibly amongst the 5 worst live bands I have ever seen, including terrible pub bands who couldn't really play their instruments. I'm trying to be impartial here, as it's not my style of music either, but honestly they were that bad.
No movement from any of them, except the guitarist kept changing between two equally terrible-sounding guitars between tracks. You want to find out what their guitarist was using, because it was all treble and presence, no bollocks whatsoever. Now I like full-on, nasty, brutal tone, but it's got to have mids and at least a few lows in there, or it just sounds thin and weedy. This guitar tone was just utterly awful.
If it's shockingly bad tone you want, copy Biffy Clyro!
