We are most proud to be one of the few US dealers of the extraordinary, Kevlar-core, handmade nylon strings by Superior Bassworks of Belgium. Superior Bassworks nylon double bass strings feature a 6 string “bump” assortment set (2 sizes of "E", 2 sizes of "G") available to the public for 1/2, 3/4, and 4/4 size double bass. The idea is that some players prefer thinner, lower tension strings while others prefer thicker, higher tension stings - you get the best of all this with 6 strings to choose from in the set! Superior Bassworks string sets also include rubber dipped metal ends. NO KNOTS to come untied in the middle of your set! They are proud to be the only company offering this feature. Superior Bassworks strings sound great whether played acoustic or amplified - they wont tear your fingers up if you need to play 3 sets in one night, and they stay in tune in hot/cold/humid/dry climates. Perfect for Rockabilly, Psychobilly, Bluegrass, Country/Western, and much much more! Stock color strings are available in Jet Black, Dirty Gut, Clear Grey, and Blood Red. This listing is for Jet Black color Standard strings.
