Steel-string

Steel-string guitars are easily the most seen acoustic guitar in North America. They look very similar to nylon-string guitars but usually have a different machine head and bridge. There are six strings made of wound steel and all are different gauges.

The sound is formed from the vibration of the strings and the sound waves moving through the body of the guitar and gaining amplification.
