Thomastik Peter Infield 3/4 G - Medium

Peter Infeld's signature for the orchestral double bass

The Peter Infeld PI61 G string is designed for musicians who want to give their double bass a denser, more precise and expressive voice. Designed for orchestral tuning, it combines projection power with tonal refinement, supporting both playing within a section and passages where the double bass needs to assert its presence more strongly.

Its spiral core benefits from a proven design, enhanced by a new combination of materials. This construction is intended to provide excellent playing stability and a consistent response, two essential qualities for maintaining reliable reference points throughout rehearsals, concerts and intensive practice sessions.

A G string for advanced and professional double bassists

This string is particularly well suited to advanced intermediate, experienced and professional double bassists looking for a responsive G string with a distinctive sonic identity. It naturally fits into symphony orchestra, chamber music, string ensemble and demanding instrumental practice settings.

Its bow response encourages a clear, controlled attack without sacrificing continuity of sound. It will appeal to musicians who want to maintain precise articulation in the upper register while benefiting from a tonal foundation that remains coherent with the rest of the double bass's range.

The sound

The Peter Infeld PI61 produces a powerful, elegant sound rich in color. Its character remains focused, with a pronounced midrange that helps the note stand out clearly within an ensemble. This presence contributes to a more legible reading of double bass lines, especially when the writing calls for rhythmic precision and consistent intonation.

Thanks to its spiral core and chrome steel winding, this G string offers a direct response under the bow. The low register retains good substance, while its sustain supports long notes, slurs and sustained dynamics. It therefore combines projection, control and tonal richness in orchestral playing.
