"Beatle" Bass set is made up of special lengths and gauges. Each handmade string is calibrated to fit the three different bridge types made by Höfner. Warm and vintage tone, excellent sustain and longevity. Fits Hofner "Beatle" basses and similar models that require 34" distance from ball-end to silk. Packaged using MAP Technology (Modified Atmosphere Packaging) to prevent tarnishing and ensure freshness. NOTICE: Please do NOT use this set to replace any of medium scale bass sets as they will not fit medium scale basses due to the string construction.
