Playability in a guitar is as important as its sound. The neck is one of the most important factors affecting the ergonomics of the guitar. Its profile is designed according to guitarist’s needs. Usually it has a standard shape, but obviously it can be done the way the guitarist is more accustomed to such as C-shape or V-shape. For semi-acoustic necks, mahogany or peer wood is used with access to the body at the 19th fret. Archtops have always had necks made of maple. The access to the body is at the 14th fret. The truss-rod can be regulated depending on your need. Guitars usually have a “standard” regulation, but, of course, you can modify it as you prefer. Satin finish is used to emphasize the flowability and smoothness of the neck. Fretboards are in ebony and have a compensated radius, designing a straight perpendicular surface along each string. This creates a balance and consistence of the action along the fretboard, avoiding buzzing of strings against frets, when playing with low action. Jumbo frets are used for acoustics and semi-jumbo frets for semi-acoustics. These characteristics, together with the quality of the frets, the nut and the inclination of the tailpiece, creates a relationship with all the parts. This gives the neck great playability and comfort, enhancing the feeling between the guitar and the guitarist.
