All FGN guitars and basses come with a unique Circle Fretting System (C.F.S.). It was created by FGN based on an idea to offer better pitch and articulation than conventional guitars and basses. All frets are installed on fingerboard in slightly curved shape, so that every string crosses all the frets in 90 degrees, i.e. to offer a minimum contact of string on a fret, and it makes the scale length of every string even while it actually varies on conventional fretting. The C.F.S. is a solution of fretting on a traditional guitar and bass and it offers clearer articulation and tones which give dimension when you play a cord and also cut through the mix when you play single notes.
