All about Rotosound Ultramag strings

We’ve attended quite a number of guitar shows so far this year and at each one, we’ve been asked the same question; why don’t Rotosound make a coated electric guitar string?

This top-grade material combines the popular tonal qualities of iron with the corrosion resistance of nickel

At Rotosound, we do things differently. Rather than jump on the coated-string bandwagon, we put our efforts into developing a long-life guitar string that didn’t lean on using a plastic coating. That’s when we discovered the alloy Type 52.

The benefits of Type 52 alloy

This top-grade material combines the popular tonal qualities of iron with the corrosion resistance of nickel. Because our Ultramag strings use an alloy rather than a coating, the protective nickel can’t be worn through, which is one of the causes of corrosion for traditional nickel wound strings.

Like other long-life strings, Ultramags will last around 3x longer than nickel wound strings but as they’re not coated they feel like regular strings (dare we say, even smoother?!). They don’t sound dull like most coated strings. In fact, because of their iron content, Ultramag strings have a strong output with solid lows and punchy mids.

What Ultramag strings are available

We currently offer Ultramag strings in the following gauges for both electric guitar and bass:
