RotosoundRS66LB Medium Light Long Scale Bass Strings
1/2
Independent shopping perspective
The Korena take
Long-scale bass strings in a medium light gauge. For four-string players who want lower tension than a standard set without going slack.
Strong match
Who this is for
- Players who bend and vibrato on bass and want less fight
- Standard-tuned four-strings with a 34-inch scale
- Anyone whose current set feels stiff under the fretting hand
Consider the trade-offs
When to look elsewhere
- Short-scale or medium-scale basses — the winding runs long
- Drop and low tunings, where light gauge goes floppy
- Five-string players; this is a four-string set
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
Medium light gauge
Lower tension than a standard set. Easier fretting and bending, slightly softer attack and less low-end push.
Detail 03
Roundwound construction
Textured winding under the fingers. Brighter and grindier than flats, and harder on frets over time.
Detail 04
Four-string set
Covers E-A-D-G. Nothing here for a low B or high C.
Final check
Know before you order
- 01Check nut-to-saddle length is roughly 34 inches before ordering
- 02Lighter tension usually means a truss rod and intonation touch-up
- 03One set only — no tools, winder, or spares
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit a short-scale bass?
No. These are cut for long-scale instruments, around 34 inches nut to saddle. On a short-scale bass the silk and taper land in the wrong place at the bridge or nut.
02Do I need to adjust my bass after switching to these?
Probably. Going to a lighter gauge drops string tension, which lets the neck pull back a little. Expect to check relief and reset intonation.
03Are these bright or warm?
Bright. Roundwound bass strings have a pronounced top end and grind when new, then settle warmer as they break in.
04Will these work for drop tuning?
Not well. A medium light gauge already runs lower tension at standard pitch, so tuning down leaves the low string loose and rattly.
