Pedal steel guitar
Pedal steels may have one or two "necks" that typically have 10 strings each. Some may have as many as 14. Unlike most other guitars, pedal steel guitars have reference lines on the fretboard. This is where frets would be, but there are no actual frets. The player changes the pitch of one or more strings by sliding a steel from one position to another while plucking the strings. Pedal steels are typically plucked with a thumb pick and fingers, or two or three fingerpicks. The pedals are mounted on a cross bar below the body. The action of the pedals may be fixed or changed by the player to select which strings the pedals affects. While there are some fairly standard pedal assignments, many advanced players devise their own setups, called copedents. The pedal steel evolved from the console steel guitar and lap steel guitar.
