The Mexican Guitarron

The guitarrón mexicano or Mexican guitarron, is a very large, deep-bodied Mexican 6-string acoustic bass played in mariachi groups. Although obviously similar to the guitar, it is not a derivative of that instrument, but was independently developed from the sixteenth-century Spanish bajo de uña. It achieves audibility by its great size, and does not require electric amplification for performances in small venues. The guitarrón is fretless with heavy gauge strings, most commonly nylon.
