What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Plain steel, unwound
No winding at this gauge, so acoustic and electric both work with the same string.
Detail 03
Single string, not a set
Replace only what broke. Cheaper than opening a fresh set for one string.
Detail 04
Acoustic or electric rated
Plain steel drives a magnetic pickup fine and vibrates the same on an acoustic top.
Final check
Know before you order
- 01This is one string, not six.
- 02Confirm your set's gauge chart before mixing in a .013.
- 03Keep spares on hand; you rarely break a string at a convenient moment.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is .013 a standard B string?
On many medium electric sets, yes. Gauge charts vary by set, so check yours before assuming the position.
02Will this work on my acoustic?
Yes. Plain steel and unwound, rated for acoustic or electric.
03Does it come in a multi-pack?
This is a single string.
04Can I mix it with a different brand set?
Yes. Gauge is what matters for fit and tension, not the brand on the envelope.
