The flamenco guitar is similar to the classical guitar but of lighter construction, with a slim body and spruce top. Tuning pegs like those of a violin are traditional, although many modern flamenco guitars have machine heads. Many young guitar players are trading their electric guitars that kill their fingertips, for a lighter, nylon string Flamenco style guitars. They have a lot of similarities in the feel of the guitar, and are more versatile than the electric ones. A distinguishing feature of all flamenco guitars is the tapping plates glued to the table, to protect them against the taps with the fingernails that are an essential feature of the flamenco style. Pinol Guitars makes them with or without pickups. Many modern soloists following the lead of "Paco de Lucía" play what is called a flamenca negra, a mixture of the flamenco and classical guitar constructions.
