What is the best way to play any string I want on a headless bass guitar?
String adapters are inexpensive, simple to use and easy to carry everywhere. Even those that swear by double ball end strings are still keeping an adapter on hand. That way in the odd case that they are traveling and a string breaks they have the option of using any set of standard single ball end strings that they want. Just nice to have that backing you up, because even if you don’t it is nice to know you could.
