Set of 4 Contrabass Strings - Type: Contrabass strings - Quantity: Set of 4 - Colors: Silver, Orange, Yellow - Material: Metal - Application: For contrabass Thank you for viewing! These are used contrabass strings (for solo tuning). They are "Belcanto" model strings. They have a soft tension and a dark, warm tone. They also have a wide and rich tone, and respond quickly to the bow. They can be used in jazz because they produce a thick, natural sustain when pizzicato. (From Kurosawa Violin) I used them for about 4-5 months, but I'm selling them because I switched to orchestra tuning strings. I don't have the original packaging, so they will be shipped in a brown envelope. There is not much twisting and the condition is good, but please check the photos and purchase if you understand that they are used items.
