An ultra-fine layer of our exclusive EXP Coating is bonded to the Phosphor Bronze wrap wire, which is then wound onto the hex-shaped core wire, resulting in a built-in barrier against corrosion and wear. EXP's sound bright and clear with new string tone that lasts 3-4 times longer than traditional strings.

Three Polishing steps produce a smooth, semi-flat playing surface without sacrificing the tone and sustain associated with phosphor bronze strings. Flat Top's smooth feel reduces surface friction and finger noise, making them ideal for recording and slide guitar.
