D'Addario J4606C Single Guitar String

Replacement Sixth String for Pro-Arté Composite Classical Sets

The D'Addario J4606C is the standalone sixth (low E) string from the Pro-Arté Composite classical guitar line, sold as a single replacement rather than a full set. Its silver-plated copper winding sits over a multifilament stranded composite core, the same construction used across the Pro-Arté Composite series. D'Addario's product description notes that this composite core delivers a powerful but warm tone that lasts two to three times longer than traditional classical strings. Hard tension gives the low E more volume and projection under the right hand, which is the main reason a player would specifically choose this variant over the normal-tension J4506C. The tie-end and uncoated finish match the original set, so a single broken string can be replaced without buying a new full set.

Who It's For

The J4606C is the right choice for classical guitarists who already play a Pro-Arté Composite set and need to replace just the low E without buying a new full set. Hard tension suits players with a stronger right-hand attack, those who want more volume and projection from the bass strings, or anyone moving up from normal tension as their technique develops. The composite core and silver-plated copper winding also appeal to gigging players who want a longer-lasting alternative to traditional gut or nylon basses. Because it is a single replacement string, it works best as a backup or repair part rather than a first-time purchase — players new to D'Addario's Pro-Arté Composite line should start with a full EJ46C set.
