In the origins of classic guitar or Spanish guitar, luthiers built their instruments inserting directly ebony pegs into the neck of the guitar. Nowadays, although modern metal machine heads are more used, there are still many constructors of Flamenco and classic guitars who prefer ebony pegs, and who are keeping alive this old tradition.
In addition, ebony pegs have some advantages. They are traditional, elegant and easy to use and to insert into the guitar. The material of ebony pegs makes them lighter and cheaper than most of the metal machine heads, and according to many luthiers, ebony pegs have a better sound.
You can take up this tradition again thanks to ebony pegs for classic guitar and Flamenco guitar in Maderas Barber.
