Standard medium-scale 4-string set for electric bass guitar from Jazz Bass 77 series that features ‘Monel’ flatwound string which have been awarded many accolades since their inception. This set has found favour with so many of the world’s top leading artists including the likes of Oasis, Steve Harris, Roger Waters and Herbie Flowers. The build specification remains a close kept secret but the Monel 400 tape used in the strings making brings out the true character of these strings over the competition. These strings are still manufactured the ‘old fashioned way’ by hand on machines that James How built at the end of the 1960’s. All Rotosound strings are manufactured in England. Gauges: .040, .050, .075, .090.
