Detail 01

The thinnest common high E. Light tension, easy bends, but goes sharp under a heavy pick attack.

Ernie BallCustom Gauge 1009 .009GA Single Acoustic or Electric String
Independent shopping perspective
The Korena take
A single .009 plain steel string sold on its own. For replacing one broken high E without opening a full set.
Strong match
Who this is for
- Restringing a snapped high E mid-session
- Stocking a gig bag with spare top strings
- Players who break the thin string more than the others
Consider the trade-offs
When to look elsewhere
- Anyone due for a full restring — buy a set instead
- Players using .010 or heavier gauge sets
- Classical or nylon-string guitars
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, so it works as a high E on electric or as a treble string on steel-string acoustic.
Detail 03
Single string
You replace one string, so it will sound brighter than the older strings around it until it settles.
Detail 04
Sold individually
Cheap insurance to keep two or three in the case rather than sacrificing a full set.
Final check
Know before you order
- 01Match the gauge to your existing set or intonation and feel will shift
- 02Ball end — will not fit guitars requiring loop-end strings
- 03One string only; no other gauges in the package
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this work on my acoustic?
Yes, if it takes ball-end steel strings. A .009 high E is light for acoustic, so it will feel slinkier than a typical acoustic set.
02Can I use it as a different string?
It's a plain .009. Some players use single plain strings for alternate tunings or lighter top setups, but it's built as a high E.
03Do I need to retune after installing?
Yes, repeatedly. A new string stretches for the first hour of playing. Pull it gently along its length to speed that up.
04How many strings come in the package?
One.
