RotosoundUltramag Bass Guitar Strings (40 - 100)
Independent shopping perspective
The Korena take
Ultramag is a .040–.100 bass string set made with highly magnetic Type 52 alloy: 52% nickel and 48% iron. That alloy is the central point of the design, with Rotosound describing greater power, sustain, and string life than traditional nickel or steel strings. It is a direct option for a bassist who wants those material-led benefits from a standard bass-string gauge range.
