This is a 5-string bass set!
Gauges: 43-51-68-89-118

They are long scale strings, intended for 34" scale length

  • This unique sounding string has a construction very similar to it's flatwound counterpart but with slightly more edge.
  • The round outer-wrap is a small diameter nickel alloy winding which ads slightly more bite to the upright style tone without the typical roundwound side effects of excessive string squeak and premature fret wear.
  • The set is designed with a lower tension and gauging to increase ease of playability and reduce strain on the instrument's neck without sacrificing output.

    expensive but fantastic string!

    Posted by Michael Gerry on Apr 13th 2021

    This is the most comfortable set of strings I have used. It has the smoothest feel and slightly less tension than my other regular strings (DR-sunbeam and low rider). If you like a tighter feel...this is NOT the string for you. It feels like a coated string, but it is not. I seem to get a very even frequency response without stating that it is bright or scooped or boomy. It just seems extremely even. I now have these strings on 2 different basses and will probably put another set on a 3rd bass. They are almost 3X the price of other strings so it is not a set of strings to impulsively buy. But I really like the strings quite a bit.

    FANTASTIC roundwounds (holy grail)--even BETTER seller!

    Posted by Island Thumper on Jan 13th 2021

    Well-worth the price; if you are curious, get these. EVEN BETTER seller; however. Asked about a strap that wasn't in stock and they just sent it to me for free with my strings. REAL PEOPLE making humanity better.
