These are Fender Original 150s pure nickel wound electric guitar strings.

For the player that wants full, warm tone, nothing compares to pure nickel.  The common misconception is that pure nickel strings are darker than the most popular nickel-steel regular versions, however that's a bit of a mischaracterisation.  In fact, pure nickel wound strings still retain a nice, bright sparkle and good clarity while simultaneously providing greater depth and a little extra warmth.

This vintage nickel wrap with hexagonal core make these Fender strings perfectly suited to a Strat or Tele where the bright, spangliness can often run away with itself; the added warmth seems to balance the tone.  They're are also gently rolled to slightly reduce finger noise for an all-round smooth sound.
