What it sounds like, and the records to hear it on.
The pedal steel guitar is a musical instrument that produces sound by strings vibrating over a magnetic pickup. The instrument has reference lines where frets would be, but no actual frets—the player changes the pitch of one or more strings by sliding a metal bar (a steel) from one position to another while plucking the strings with the other hand, or vibrating them with a mechanical device. Pedal steels may have one or two "necks" that typically have 10 strings each, but may have as many as 14. .
