This was one of the first strings in the world that had a diagonally-flat wound string. It is made with Monel, a vintage alloy made up of Nickel and Copper which delivers great resistance to corrosion and is able to stand a lot of tension. The Monel provides the player with a warm round sound with a smooth feel. It delivers a deep tone with a bit of an upper harmonic bite.
These strings are still made by hand with machines built at the end of the 1960's, with all this history, the Jazz Bass 77 do not disappoint. They have been endorsed by artist like Roger Waters and Steve Harris.
