.013 - .056 Medium Gauge Acoustic Guitar Strings, Phosphor Bronze
 
Nanoweb coating provides an uncoated feel and natural sound.
Special full-string coating prevents grime from collecting between the coils and deadening your sound.
Extra-long-life coating lasts much longer than typical coatings.
Phosphor bronze delivers a characteristically vibrant and focused sound.
An ideal string for warming up and defining dark guitars, such as those made of mahogany.
