Independent shopping perspective
P02805 is a 45–105 flatwound electric bass set built with polished stainless-steel ribbon winding. The polished surface is intended to minimize squeak and friction as the hand moves along the neck, supporting controlled slides, bends, and vibrato work. Ernie Ball precision-winds these strings with custom gauges, core sizes, and wrap ratios to maintain consistency. They are produced in the company’s Coachella, California factory and are one of three available flatwound gauge options.
