Overview

The D'Addario Kaplan Double Bass E String is part of D'Addario's premium orchestral line, specifically scaled for 3/4 size double basses. This heavy tension variant is designed to meet the rigorous demands of professional orchestral environments. The string is constructed to balance the needs of both arco (bowed) and pizzicato (plucked) techniques, ensuring versatility across a standard symphonic repertoire.

Performance and Bowing Response

A primary design focus for the Kaplan series is its bowing response. The string is engineered to provide immediate engagement with the bow, allowing for precise articulations and clarity in both the lower and higher registers.

Tonal Character

The sonic profile of the Kaplan E string is characterised by warmth and depth. When played pizzicato, the string produces a full, rounded tone without excessive sustain or brightness, which is often preferred for maintaining a traditional deep bass foundation. Overall, the string provides a balanced clarity that prevents the low E from becoming muddy, maintaining definition even in the lowest register of the instrument.

Comparison to Alternatives

Within the D'Addario catalogue, the Kaplan stands as a specialized orchestral choice compared to the Helicore series, which offers variants for different playing styles (such as Hybrid or Pizzicato). While strings like the Thomastik Spirocore are often noted for their long sustain and brightness—favoured by jazz players—the Kaplan is specifically voiced to suppress these traits in favour of a more controlled, orchestral timbre. Compared to lower-tension strings, this heavy tension E string offers more resistance under the fingers, which can be beneficial for players with a strong technique looking for maximum projection.
