Detail 01
.125 gauge
On the heavier side for a B. Tighter feel and less flop, but it needs a nut slot that fits.

1/3
Independent shopping perspective
The Korena take
A single .125 low B string for five-string bass. For replacing a dead or broken B without buying a whole new set.
Strong match
Who this is for
- Players who wear out the B faster than the rest
- Keeping one spare in the gig bag
- Matching a .125 B to an existing Hi-Beam set
Consider the trade-offs
When to look elsewhere
- Anyone needing a full restring — this is one string
- Four-string basses, which have no low B
- Setups built around a lighter or heavier B gauge
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
Single string, not a set
Replaces the B only. The other four keep whatever age and tone they already have.
Detail 03
Medium
Matches the B from a medium five-string set, so it sits evenly alongside the other four.
Detail 04
Five-string bass string
Sized for the low B position. Far too heavy to tune up and use as an E.
Detail 05
Hi-Beams line
Same family as a Hi-Beam set, so feel and output line up if that is what is already on the bass.
Final check
Know before you order
- 01One string only — no E, A, D or G
- 02Check your nut slot; a .125 may need widening to seat
- 03A fresh B next to four worn strings can sound mismatched
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this a full set?
No. One .125 low B string. If your other four are the same age, buy a five-string set instead of a single.
02Will .125 fit my bass?
Most five-strings are cut for a B in this range, but slots vary. If it binds in the nut, have the slot widened rather than forcing it.
03Will it match my current strings?
It lines up with a Hi-Beam set. Against a different brand, or four worn strings, expect a noticeable difference in brightness.
04Do I need to adjust anything after fitting it?
Check intonation at the B saddle. The truss rod usually stays where it is when only one string changes.
