Up to eleven From Wikipedia, the free encyclopedia "Up to eleven", also phrased as "these go to eleven", is an idiom from popular culture, coined in the 1984 movie This Is Spinal Tap, where guitarist Nigel Tufnel proudly demonstrates an amplifier whose volume knob is marked from zero to eleven, instead of the usual zero to ten. The primary implication of the reference is one in which things that are essentially the same are seen as different, due to mislabeling or the user's misunderstanding of the underlying operating principles. A secondary reference may be anything being exploited to its utmost limits, or apparently exceeding them. Similarly, the expression "turning it up to eleven" refers to the act of taking something to an extreme. In 2002 the phrase entered the Shorter Oxford English Dictionary with the definition "up to maximum volume".

The use of "11" as a maximum pre-dates This Is Spinal Tap by almost forty years. In 1947, the Baldwin Locomotive Works and the Chesapeake and Ohio Railway introduced the Chesapeake and Ohio class M-1 steam turbine locomotive. The locomotive's throttle included eleven settings, ranging from one (idling) to eleven (full speed). The locomotive's cruising speed was 70 miles per hour (110 km/h), at which point the throttle was on "seven". During a trial run with a reporter from Popular Mechanics aboard, a C&O engineer expressed his dissatisfaction with a local speed limit of 75 miles per hour (121 km/h), noting that he would "Sure like to be able to pull it back to eleven!" Gibson Les Paul guitars with low-impedance pickups were outfitted with special controls designed by Les Paul himself. Controls included a "Decade Switch" which went up to 11.
