What factors affect string tension?

    I've got a question for anyone out there:

    I can have two very similar basses, let's say two P-style basses. They'll have the same strings, same neck scale, same string height, same type of bridge. Nevertheless, on one, the strings will feel looser and more flexible, while the other will feel tighter and stiffer. What factors contibute to this?

    Neck stability?

    The only factors, in all reality, that should affect string tension are the string gauge, their age (strings tend to loosen up with age), and the sale (ringing) length of the string.

    Neck relief would be my answer. Even a slight difference will make the strings seem stiffer.
  6. That isn't true. Neck relief has no bearing on string tension. The operative term in your post is "seem". Perceived tension and the actual measurable tension are often two completely different things

    The key difference between tension and feel is that feel is a dynamic thing. A perfect string of a given mass per unit length will always have the same static tension for a given tuning and scale length. But as soon as you pluck it, the vibration and movement of the neck, body and hardware and the stiffness of the string come into play. Furthermore, when you fret a note the tension changes slightly and the effort to fret a note depends on the action and relief, which affects the feel.

    I know for me, there are often completely unrelated and illogical things that make the "feel" change. The clearest example is this: I am of the "willis ramp" school, sort of. I like the pickups up high enough so that I can't dig in. I play over the bridge pickup, fwiw. OK, so on a bass with the same measured sting height, but a lower pickup height, or greater pickup/string distance, my FRETTING hand feels different. Odd?? yes. Do I need electro-convulsive therapy to fix this?? who knows. It could be that something seemingly unrelated to what you are perceiving is the actual cause.
  9. This is most-likely due to the fact that as your pickups become more or less sensitive, your fretting technique must compensate to mitigate things like fret-noise.

    It's all about TOUCH....TOUCH IS 99.5% of bass playing. BTW...guitarists have no idea.

    Wouldn't scale length affect tension?

    Tension won't be different between the two but the
    feel can definitely be different. If the strings feel
    really stiff in first position the nut height is probably to high.
    A difference of .020 can be felt quite easily. This applies to the original post.
