Most hollow body electric guitars are fitted with three unwound plain steel strings (strings 1- 3) and three nickel wound onto steel strings (strings 4 - 6). Some Jazz guitarists however prefer the option of using a wound third string, as shown in the adjacent photo. This configuration, particularly used in conjunction with flatwound strings will give a more mellow sound.
Generally Jazz guitarists (and in many cases Blues players) will also opt for a heavier gauge string than that is used on solid body electric guitars.
Fixing the string to the bridge: The most common bridge setup on a hollow body electric is a fixed tailpiece system. The string is either inserted through a hole in the tailpiece and restrained by the ball end of the string or the ball end is secured in a slot cut out of the tail piece. Both tailpiece types make fitting the string simple.
Fixing the string to the tuning key: Strings are fixed to the tuning keys of a hollow body electric in the same way as a solid body electric (see page 9).
