Tail wire loop assembly for bass, by New Harmony Music - 24" length of coated stainless steel cable, with a fully adjustable brass connector. The importance of a properly-tuned afterlength and tailwire material compatibility with your bass, string choice, and setup can't be overestimated! This kit allows for precise adjustment of the afterlength and maximal freedom of vibration with ample tensile strength. We strongly recommend having a good working knowledge of bass setup if you're choosing to order this assembly. You'll need an Allen wrench, cable cutter, wire stripper/knife, and knowledge of how to use them and how to take down the setup of your bass in order to successfully install it - or, have us install it for you.
