D'Addario K611 3/4M Double bass Strings

Kaplan Bass Single G String — 3/4 Scale, Medium Tension

The Kaplan Bass Single G String is a standalone replacement G for 3/4-scale orchestral double bass, part of D'Addario's Kaplan professional line. Built on a stranded steel core — steel wires braided together into a flexible cable — this string is engineered for the most discerning orchestral musicians who need quick bow response, clarity across registers, and control through the full dynamic spectrum. Medium tension sits between the light and heavy options in the Kaplan range, giving the G voice a firm, articulate character that holds its own in both solo and ensemble settings. The ball-end fitting matches standard orchestral double bass tailpieces, so swapping out a worn G is straightforward without modifying the instrument.

Who It's For

The Kaplan Single G String is the right choice for advanced students, conservatory players, and professional orchestral bassists who need a reliable replacement G for a 3/4-scale instrument. It suits players working in orchestral sections, chamber ensembles, and solo repertoire where quick articulation and an even tone across the fingerboard matter most. Medium tension pairs naturally with the rest of the Kaplan 3/4 Medium set, so the G integrates cleanly with Kaplan A, D, and E strings on the same instrument. Players who prefer a lighter or heavier feel can step to the Kaplan 3/4 Light or 3/4 Heavy variants without changing the stranded steel core construction or ball-end format.
