D’Addario XL ProSteels utilize an exclusive corrosion-resistant steel alloy that delivers super-bright tone without shrill overtones. They offer a palette of harmonically rich, brilliantly penetrating highs combined with pronounced, tight-and-tough lows.

“I use the ProSteels 45-105 (and a 130 tapered core B) for the sweetest, most pleasingly bright sound I can get when I really need that chime and attack. When I put them on a warmer sounding instrument, they provide the right bloom in the note. They just do everything right, and they’re extremely dependable and long-lasting.” – BRYAN BELLER
