Marty DiBergi: Oh , I see . And most amps go up to ten ?
Nigel Tufnel: Exactly .
Marty DiBergi: Does that mean it 's louder ? Is it any louder ?
Nigel Tufnel: Well , it 's one louder , is n't it ? It 's not ten . You see , most blokes , you know , will be playing at ten . You 're on ten here , all the way up , all the way up , all the way up , you 're on ten on your guitar . Where can you go from there ? Where ?
Marty DiBergi: I do n't know .
Nigel Tufnel: Nowhere . Exactly . What we do is , if we need that extra push over the cliff , you know what we do ?
Marty DiBergi: Put it up to eleven .
Nigel Tufnel: Eleven . Exactly . One louder .
Marty DiBergi: Why do n't you just make _ ten _ louder and make ten be the top number and make that a little louder ?
Nigel Tufnel: These go to eleven .
