Sfarzo Alloy 5109 Phosphor Blend Acoustic Guitar Strings 12-54
 
ALLOY5109 - Responsive and sweet. Using a newly developed alloy for electric guitar use, these strings have greater than ever magnetic properties thereby increasing their tone, sustain and projection. A microscopic coating adds to their lifespan, corrosion resistance and decreased fret wear. Also, the proportion of winding to core size has been increased which ups the string vibration without lowering the output. Each set undergoes excellent quality control, so you can be assured of string reliability and consistency each time you purchase a set of Alloy 5109 strings.
