    Hi there. I have somewhat of a lack of definition on my low B string. A typical fully-wound (i.e.; not tapered) string is too fat to fit into the groove in the saddle - more like sitting on the two outer edges of the groove.

    Is this a common problem? Do I need to use tapered strings (where the inner core will be thin enough to fit into the groove) and will the tone then suffer in comparison to the other, non-taper strings?

    A photo may help.

    I don't think it's usually an issue to have the string sit the way you describe. I think it's the the approach and departure angels that I sometimes had an issue with, along with "setting the witness point" on these heavy-gauge strings.

    Are you putting a B sized string on a 4 string bass?

    I know the problem you are talking about. The saddle has to support the string while avoiding "choking" it. It needs to be able to vibrate properly to have clarity. Getting a low B right is a tricky thing.

    What is the gauge of the string and brand/model? What bass is it? What is the scale length? These can all make a difference.

    It's not ideal for a string to be riding up on 2 points on the saddle, that creates a more rigid pivot that reduces freedom to vibrate.
    Also, taperwound strings have better tone, flexibility, clarity, sustain than non-taperwounds, try one.

    But don't forget the compromises - mostly with respect to intonation. An ideal string would have its mass evenly distributed along its vibrating length, which would lead to the best intonation. With taper windings the mass is not evenly distributed and can lead to intonation issues. As with many other things in instrument design, it's a matter of compromise, so it's best to know what compromises you are dealing with.

    I agree. With taperwound strings it's a good idea to minimise the length of tapered section in the vibrating length (should be no more than an inch, preferably less). Some brands have excessively long tapered sections. I should have mentioned this earlier.
    It may be possible to add spacer sleeves to the string to pull it back through the bridge a little.

    Thanks for the advice guys. I have been using tapered strings but have bought a set of Dunlop tapered B mediums to replace. I'd never heard of the witness point until recently. I'll try and set that properly when I load the new strings. That might also account for the fact that the low B intonation was never right - even with the saddle moved right the way back it was not enough to sort it
