| If your bass has a lighter set, (it probably does) than those, be aware that changing to the heavier set will most likely require a set up on your bass. Judging by your question, that would be something you'd need to have done by a professional luthier, and may cost anywhere from $25-$65. IOW, don't use those strings, unless your bass already has the exact same ones on there now, or you'll have a set up done.
