Pirastro Flexocor D Double Bass String, 3/4 - Heavy

Pirastro Flexocor D Double Bass String

The Pirastro Flexocor D Double Bass String combines a carbon steel rope core with chrome steel winding for a warm orchestral sound. Designed especially for arco, or bowed playing, this 3/4-size string offers quick response and short sustain. Choose light, medium, or heavy gauge to suit your instrument's setup.

For bassists selecting an orchestral replacement D string, the three gauges provide different tension levels within the same construction. Light carries the lowest load, medium provides an intermediate tension, and heavy carries the highest. Musicians choosing a steel-core string for bowed repertoire can compare these specifications when refining their setup for rehearsals, concerts, and classical ensemble work.

Pirastro specifies ball-end attachments and ruby tailpiece silk across all three options. Rust red peg-end markings identify the D string, with additional colors distinguishing light and heavy versions. The series supports stable tuning and readiness after installation. Each configuration fits a 3/4 double bass in orchestra tuning and uses a separate manufacturer article number for accurate replacement selection.
