Skilled Danish craftsmen still make Jargar strings by hand in Copenhagen, just as they have since 1956 when Danish cellist Jarl Hansen formed the company to pursue his quest to build better strings. The Jargar double bass strings come in three versions and are commonly identified by the colors of their ball ends. The forte double bass strings with red ball ends are the thickest of the three gauges and are made for orchestra tuning. Choose the dolce or green strings for solo tuning. All three versions of Jargar double bass strings use alloy windings around a twisted wire core to provide superb response and a warm and brilliant tone.
