NIGEL: Well, it’s one louder, isn’t it? It’s not ten. You see,
most...most blokes, you know, will be playing at ten. You’re on ten
here...all the way up...all the way up....
NIGEL: ...all the way up. You’re on ten on your guitar...where can you go from there? Where?
MARTY: I don’t know....
NIGEL: Nowhere. Exactly. What we do is if we need that extra.. push over the cliff...you know what we do?
MARTY: Put it up to eleven.
NIGEL: Eleven. Exactly. One louder.
MARTY: Why don’t you just make ten louder and make ten be the top... number... and make that a little louder?
NIGEL: These go to eleven.
Got to watch the movie for it to be funny, hehe
