Why you need the D Addario NYXL0946 Nickel Wound, Super Light Top Regular Bottom Electric Guitar Strings, 09-46 This hybrid set of strings combines from the low strings a regular light set (.046) with the high strings from a super light set (.009) resulting in more flexibility on the high strings and more fundamental on the lower end. These strings last longer, are much louder, bend more and stay in tune like no other string. With these string's greater magnetic properties, they provide higher output and a more enhanced mid-range frequency.
