Exit Music (for a film) by Radiohead. I believe the bass fuzz is a muff -- awesome bass line.
Nope. Pretty much any bass fuzz on a Radiohead recording is going to be a Shin-ei Champion Fuzz (Exit Music, The National Anthem, Myxomatosis). They are all still really awesome, though.
Although, last time I checked, he was using a Lovetone Cheese Source to get those tones live.
