Detail 01
Heavy gauge
More tension per string. Stays tight in low tunings, but bends and vibrato take more finger strength.

DunlopHeavy Core 7-String Electric Guitar Strings - Heavy Gauge
Independent shopping perspective
The Korena take
Heavy-gauge 7-string set for down-tuned electric guitar. For players who tune low and want the low B to stay tight.
Strong match
Who this is for
- Drop-tuned metal and djent on a 7-string
- Players whose low B goes floppy on lighter sets
- Longer-scale 7-strings that handle high tension well
Consider the trade-offs
When to look elsewhere
- 6-string guitars — the extra string has nowhere to go
- Standard-tuned players who want easy bends
- Vintage-style trems and thin necks that dislike added tension

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my 7-string with a Floyd-style bridge?
Yes, but the added tension changes the float. You'll need to rebalance the spring claw and reset intonation after installing.
02Can I use these in standard E tuning?
You can, but heavy gauge in standard is stiff. Bending and vibrato get much harder. Lighter sets suit standard tuning better.
03How many strings come in the pack?
Seven — a full set for one 7-string guitar, including the low B.
04Do I need to adjust my guitar after switching to these?
Usually yes. Heavier strings pull the neck forward and shift intonation. Expect a truss rod tweak and saddle adjustment.
