D'Addario KS513 4/4M G 4/4 Cello Strings

Kaplan Cello G String — Professional Tone for the 4/4 Cellist

The D'Addario Kaplan Cello Single G String, 4/4 Scale, Medium Tension, is a replacement G string designed for full-size cellists who want the tonal depth and bow response of a professional orchestral string. Conceived for the most discerning musicians, this string stands up well to extreme bow pressure and allows a diverse tonal palette. Inside the cable-style stranded steel core, braided steel wires blend strength with flexibility, producing a balance of clarity and complexity that translates into a powerful but warm sound on the lowest string of the cello.

Where many G strings either sound thin or lose definition under heavy bowing, the Kaplan G maintains its rich and complex character. The tungsten winding adds mass to the foundational bass note without dulling the response, giving the instrument a bottom end that supports both solo repertoire and ensemble playing. Cellists who have previously relied on European tungsten G strings will find that this USA-made alternative eliminates the occasional snarl while keeping the rich, warm, projecting bass intact.

Who This String Is For

The Kaplan Cello Single G String is the right choice for professional cellists and advanced students who need a single replacement G string that matches the rest of a Kaplan set. Its stranded steel core and tungsten winding give it the projection and clarity required for solo performance, while the medium tension suits the bowing style of most players. Players upgrading from entry-level factory strings will notice an immediate improvement in tonal depth and bow response, even on instruments at the lower end of the cello market.

Designed, engineered, and manufactured in the USA at D'Addario's New York production facility, this string is built to the same quality standards as the full Kaplan cello line, making it a reliable option for cellists who want consistency across all four strings. The medium tension option is optimized for the needs of a majority of players, while light and heavy tension variants are available for cellists who prefer a different feel under the bow.
