D'Addario J4403 Single Guitar String

Extra-Hard Tension G String for Classical Guitar

The D'Addario J4403 Pro-Arte single string is the 3rd (G) string from the EJ44 Extra-Hard Tension set, sold individually for players who only need to replace one worn or broken treble. Made from clear nylon — the traditional material for classical guitar trebles — it produces the bright, articulate tone that Pro-Arte is known for. Extra-hard tension gives the G string a firmer feel under the fingers and noticeably more volume and projection than normal or hard tension alternatives, which suits players with a stronger right-hand attack or those tuning down to lower pitches. Buying a single replacement also avoids the cost and tonal disruption of restringing the whole guitar when only one string has worn out.

Who It's For

The J4403 is the right choice for classical guitarists who play with a firm right-hand technique and want maximum volume and projection from their G string. Extra-hard tension suits flamenco-influenced players, traditionalists who prefer the resistance of higher-tension setups, and anyone whose G string has broken or lost its brilliance before the rest of the set. It fits any standard classical guitar and ties at the bridge like other Pro-Arte trebles, making it a straightforward drop-in replacement for an existing EJ44 or Pro-Arte Extra-Hard setup.
