Founded in 1946, Fender Musical Instruments Corporation has been an American icon for over 50 years. In that time, Fender’s contribution to the evolving sound of contemporary music has been global and continuous. By introducing the first commercially viable solidbody electric guitar, the first electric bass and countless classic amplifiers, Fender musical instruments have left their mark on jazz, blues, country, rock and many other styles of popular music. Fender has also been making strings nearly as long as they've been building guitars, and they've got it down. The Original 150s deliver the warm, full tone found only in pure nickel strings. Nickel plated Steel Super 250s are installed at the Fender factory on all U.S. and Mexico non-tremolo electric guitars as original equipment. So if you want to keep your guitar "factory fresh," look no further!
