Bass guitar the 3rd, 5th, 7th, 9th fret and 12th fret (the 12th fret being the octave of the open string) and on the octave-up equivalents of the 3rd fret and as many additional positions as an instrument has frets for. Typically, one marker is on the 3rd, 5th, 7th and 9th fret positions and two markers on the 12th fret. The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of — set the standard for electric basses, although "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the
Zero fret the advantages and the drawbacks of modern guitar manufacturing. The high string tension makes the instrument almost implayable for beginner students, especially for children, and additionally serves to spoil the ear training for harmonies and tone intervals due to intonation errors. Luthier intervention is required in such cases. High string action at the nut is often preferred to avoid string buzz with heavy playing style. The lower fret area is therefore out of tune. A partial solution is to apply nut corrections by reducing the distance from the nut to fret one for a small amount and then re-tune the
