D'Addario J4605C Single Guitar String

Replacement 5th String for Classical Guitar

The D'Addario J4605C Pro-Arte is a single replacement 5th (A) string designed for classical guitar sets that use the Pro-Arte Composite line. When one bass string wears out before the rest of the set, replacing just that string saves money and keeps the rest of your playing setup intact. The hard tension gauge gives the A string a fuller, more projecting voice that suits expressive playing and louder dynamic ranges. At the heart of this string is an exclusive multifilament composite core, which delivers a warm, powerful tone while lasting 2-3 times longer than traditional nylon bass strings. The silver-plated copper wrap is precision laser-sorted to keep diameter and tension consistent from one string to the next.

Who It's For

The J4605C is the right choice for classical guitarists who need to replace a single worn 5th string without buying a whole new set. It fits players who already use D'Addario Pro-Arte Composite strings and want to keep the same tone and feel across the bass register. Hard tension works well for fingerstyle players and performers who want a stronger attack and more volume from the A string. The composite core also suits players who play often and want a string that lasts noticeably longer than standard nylon. Because it is a tie-end string with no ball, it installs the same way as the original Pro-Arte Composite 5th string on any standard classical guitar.
