"It's very special, because, as you can see --the numbers all go to 11. Right across the board. Eleven...11... And most amps go up to 10? Exactly. Does that mean it's louder? Is it any louder? Well, it's one louder, isn't it? It's not 10. You see, most blokes are going to be playing at 10 -- you're on 10 on your guitar, where can you go from there? Where? I don't know. Nowhere! Exactly! What we do, if we need that extra push over the cliff, you know what we do? You put it up to 11. Eleven. Exactly. One louder."
--Nigel Tufnel explaining his amplifier in "This is Spinal Tap"
