Thomastik Peter Infield 3/4 Mi - Medium

An E string designed for demanding double bassists

This Peter Infeld E string is intended for musicians looking for a solid, expressive and stable low-end foundation. It combines generous sonic presence with a controlled character, without sacrificing the precision required for orchestral playing. Its balance particularly enhances the midrange, an appreciated quality for maintaining clarity in full sections as well as in more restrained dynamics.

Designed for a 3/4 double bass with a vibrating length between 1030 and 1100 mm, it is suitable for instruments used in orchestral tuning. Its tension has been designed to offer a firm, responsive playing feel while preserving a broad response in the lower register.

Which musicians and playing styles is it suited to?

This double bass string is primarily suited to advanced intermediate, experienced and professional musicians looking to reinforce the presence of their low register. It is particularly well suited to classical music, symphonic repertoire, chamber music and settings where stable intonation and a clean attack are essential.

Its excellent response to the bow allows double bassists to work on dynamic changes, strong attacks and sustained notes with greater control. Thanks to its rich tone and sustain, it can also appeal to players looking for an E string capable of supporting a dense bass line without losing definition.

The sound

The character of this string is based on a spiral core combined with a chrome steel winding. This construction promotes a direct response, even projection and good stability over time. The low register retains its depth, while the midrange remains present and focused, helping the double bass maintain its place within the ensemble.

On an acoustic double bass, the final result also depends on the top, back, ribs, bridge and the instrument's overall setup. Nevertheless, this E string provides a clearly defined sonic foundation, with an elegant color and beautiful note sustain. It responds efficiently under the bow and makes it possible to develop a full, articulate and homogeneous sound throughout the low register.
