ThomastikAB345 Acousticore Phosphor Bronze 5-String Bass Strings
Independent shopping perspective
The Korena take
Phosphor bronze acoustic bass strings in a five-string set. For acoustic bass guitars with a low B, not electric basses.
Strong match
Who this is for
- Acoustic bass guitar players who need a low B string
- Restringing a five-string acoustic bass with all five at once
- Players wanting bronze warmth over bright steel
Consider the trade-offs
When to look elsewhere
- Electric bass players — bronze needs a magnetic pickup to work poorly
- Four-string basses; this set includes a fifth string
- Anyone on a tight budget — this sits well above entry-level set pricing
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
Acousticore construction
Built for acoustic bass, where the body does the amplifying. Response differs from a steel electric bass set.
Detail 03
5-string set
Includes the low B. Your bass needs five tuners and a nut slotted for the extra string.
Detail 04
Full set, not singles
All five strings in one package. Restring together so tension and tone stay even across the neck.
Detail 05
Bronze wrap
Bronze is not magnetic in the way steel is, so it responds poorly to standard magnetic bass pickups.
Final check
Know before you order
- 01Confirm your acoustic bass has a nut slot wide enough for the low B
- 02Bronze does not drive magnetic pickups well — check your bass uses a piezo
- 03Check scale length against your instrument before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use these on an electric bass?
Not well. Phosphor bronze does not drive magnetic pickups the way steel strings do. These are for acoustic bass.
02Will these fit a four-string bass?
The set includes five strings. You would be paying for a low B you cannot use, and the gauges are matched as a five.
03How do phosphor bronze strings sound compared to plain bronze?
Warmer and less brittle in the top end, and they tend to hold that tone longer before dulling.
04Do I need to change all five at once?
Not required, but changing the full set keeps tension and tone even across the neck. Mixing new and old strings sounds uneven.
