Length: 43 Inches Plain ball-end strings are made from tin-plated, high-carbon steel. This type of wire is considered spring wire. These strings are used on both electric and acoustic guitars.
These stings hold up well even in the face of vigorous bending. They're noticeably louder than other strings of the same gauge. They stay alive for a long time and still intonate perfectly. Truly a miracle string. The wounds are also good, however the plains are where it's really at.....In my opinion.
