Strengths

  • Vintage tone: Customers consistently praise the strings for delivering a true vintage tone, often described as rich with low mids and capable of cutting through the mix.
  • Comfortable feel: Many users highlight the strings' comfortable and smooth feel, making them pleasant to play and reducing finger fatigue during extended sessions.
  • Low tension: The strings are noted for their exceptionally low tension, which allows for faster and more expressive playing, and is also suitable for basses with sensitive necks.
  • Durability and intonation: Customers report that the strings maintain their intonation well over time and show minimal alteration in sound, justifying their higher price point.

Weaknesses

  • Requires technique adjustment: The very low tension of these strings means that precise fretting hand technique is needed to avoid accidental string bending, and players accustomed to high-tension strings may need an adjustment period.
  • Neck adjustment: Some users note that basses previously set up with high-tension strings might require a neck adjustment to accommodate the lower tension of these strings.

What customers repeat

“By far the best.” “Great strings that might not have that flatwound thump.” “Extremely low tension.” “Very pleasant to the touch.” “Best strings I've had in the last 30 years.” “The sound alters imperceptibly over time.”

Verdict

These flatwound bass strings are highly regarded by customers for their unique tone and comfortable playability, making them suitable for bassists seeking a vintage sound and a lighter touch. While they offer exceptional feel and sound, their low tension requires an adjustment period and precise technique.

I’ve been using these strings for many years on both my Jazz Bass and Precision bass. I’ve tried many different flatwound strings, but in my opinion these are by far the best. They offer a comfortable feel, great durability, and a true vintage tone. Give them a try—you won’t be disappointed.

Aceste corzi sunt standardul in ceea ce priveste flat-urile! Sunetul se altereaza insesizabil in timp iar corzile isi pastreaza intonatia. Asa se justifica pretul peste medie.
