Phosphor bronze
Warm, woody voice that projects acoustically. Bronze is non-magnetic, so it's built for acoustic bass, not magnetic pickups.

ThomastikAB344 Acousticore Phosphor Bronze 4-String Bass Strings
Independent shopping perspective
The Korena take
Phosphor bronze strings for four-string acoustic bass. A specialty set — buy these if you actually own an acoustic bass guitar, not an electric one.
Strong match
Who this is for
- Acoustic bass guitar played unplugged in a room
- Players who want warmth rather than bright zing
- Replacing worn strings on a four-string acoustic bass
Consider the trade-offs
When to look elsewhere
- Electric bass — phosphor bronze won't drive magnetic pickups well
- Five- and six-string basses; this covers four only
- Anyone wanting a bright, aggressive slap tone
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
Four-string set
Covers standard E-A-D-G. No fifth or sixth string, so five-string players need a different set.
Detail 03
Acousticore construction
Core designed for acoustic bass tension and scale length, which is longer than a standard guitar.
Detail 04
$114.95 per set
Well above typical bass string pricing. Expect long service life to justify the cost rather than frequent changes.
Detail 05
Bass scale length
Made for a long-scale instrument. Short-scale acoustic basses may leave excess winding at the tuners.
Final check
Know before you order
- 01One set of four strings — no picks, tools or extras included
- 02Confirm your bass is acoustic, not an electric with bronze-friendly pickups
- 03Measure your scale length before ordering; long-scale is the assumption
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I put these on an electric bass?
Not recommended. Phosphor bronze is non-magnetic, so magnetic pickups produce a weak, uneven output. Use nickel or stainless strings on an electric bass.
02Do these fit a five-string bass?
No. This is a four-string set covering E-A-D-G. You'd need a separate low B string or a five-string set.
03Why do these cost more than typical bass strings?
Thomastik strings are built to a different construction standard than mass-market sets. Whether that's worth it depends on how long they hold their tone for you.
04Will these work on an acoustic bass with a pickup?
Yes if the pickup is piezo or under-saddle, which senses vibration rather than magnetism. Magnetic soundhole pickups won't read bronze well.
