D'Addario CG030 Single Guitar String

D'Addario CG030 Flat Wound Electric Guitar Single String

The D'Addario CG030 is a single replacement string from the Chromes flatwound lineup, sized at .030" (0.76 mm) for electric guitar. Its flat wound stainless steel construction produces the smooth, mellow tone that has made D'Addario Chromes a go-to choice for jazz, blues, and surf guitarists. The coated finish helps the string resist corrosion and tone loss between playing sessions, extending its usable life compared to uncoated flatwounds. A hex core anchors the winding securely, giving the string stable tuning and reliable intonation whether it sits in the D or G position of a standard set. As a single-string purchase, it lets players replace one broken or worn string without buying a full set, or build a custom gauge combination to suit their instrument and playing style.

Who It's For

The CG030 is the right choice for electric guitarists who want to maintain or build a flatwound setup without buying a full set. Jazz players chasing that classic warm, rounded tone will appreciate how the .030" gauge slots into the D or G position of a standard Chromes set. Lap steel and surf guitar players benefit from the smooth finger feel and the way the coated stainless steel winding holds up to heavy picking. It's also a practical pick for anyone who needs to replace a single broken string on an existing flatwound guitar — no need to discard the rest of the set. Beginners exploring flatwound tone for the first time can start with a single string to hear the difference before committing to a full set.
