Rotosound UM9 Ultramag Electric Guitar String

High energy at your fingertips!

Our new Ultramag strings are made with type 52 alloy – a highly magnetic material made from 52% nickel and 48% iron.

This blend gives Ultramag strings more power, sustain, and a longer string life than traditional nickel or steel strings.
