    i am wondering whats the logic if you take the same string on a bass with 103cm scale vs 106cm scale, everything else equal.
    more tension on the shorter scale?

  3. New_Tension=Measured_Tension * ((New_Stringlength / Measured_Stringlength) ^ 2)

    If you don't known the "measured" tension, set it to 100 and you get the result in perfekt of the "measured" length tension.

    And the answer to your question is:
    Same string, same pitch, shorter scale -> lower tension

    very interesting, thanks!
    but of course the "feel" for the left hand - other factors like angle after the bridge, the top of the bass, and so on also have a huge impact.
     
  5. The stretch of the string core has a huge impact of felt tension. Synthetic and gut cores stretch easier than steel cores, so steel core feels like harder tension to the left hand with a high action, there is not so much felt difference with synthetic or gut cores. The stretch factor also depends on the diameter of the core, thin ones stretch easier than thick ones.
    But also the top of the bass and the bridge influences the felt tension.
