Detail 01
Coated
A thin surface layer keeps sweat and skin oil out of the windings, so the set holds its tone longer.

Ernie Ball3121 Coated Titanium Slinky Electric Guitar Strings
1/2
Independent shopping perspective
The Korena take
Coated electric guitar strings from Ernie Ball's Titanium Slinky line. For players whose sweat eats uncoated sets fast, or who want fewer string changes.
Strong match
Who this is for
- Players whose hands kill uncoated strings within a week
- Gigging guitarists who want longer stretches between changes
- A guitar left on a stand between sessions
Consider the trade-offs
When to look elsewhere
- Players chasing the raw bite of fresh uncoated strings
- Anyone changing strings weekly anyway — the coating is wasted
- Acoustic, classical or bass — this is an electric set
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
Slinky family
Ernie Ball's electric naming system. Match the set number to what is on your guitar now before you switch.
Detail 03
Titanium Slinky, not plain Slinky
A separate variant within the Slinky range; durability is the point of difference, not a different playing family.
Detail 04
Electric guitar strings
Built to drive magnetic pickups. On an acoustic they will sound thin and quiet.
Detail 05
$12.99 a set
A few dollars over a plain set. Only worth it if you actually leave them on longer.
Final check
Know before you order
- 01One set of six strings, not a multi-pack
- 02Changing gauge can mean a truss rod and intonation check
- 03Coating can flake at heavy bend points over time — normal wear
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How much longer do coated strings actually last?
Longer than uncoated for most players, since the coating blocks sweat and oil. How much longer depends on how acidic your hands are and how often you play.
02Do coated strings sound duller?
Slightly less top-end zing on day one than a fresh uncoated set. The trade is that they hold that tone instead of dropping off after a few days.
03Will these fit any electric guitar?
Yes for standard six-string electrics. With a Floyd Rose or similar locking system you clip the ball ends off first.
04What gauge are these?
Check the set number on the pack against your current strings. Slinky names carry the same gauge meanings across Ernie Ball's electric lines.
