Pyramid Nickel Classics 12-54 Guitar Strings
 
Developed for guitarists with the highest demands on tonal quality.
The special thing about this product is the round core wire of the wound strings.
The improved construction with a round steel core and pure nickel wrapping leads to clean vibration behavior of the strings.
The PYRAMID Nickel Classics have a significantly improved vibration behavior, which leads to a very long decay of the string (sustain) and an even development of the tone.
A product with the well deserved designation: "Premium Classics".
