What is the difference between ball end, loop end and removable ball end?

Previously, gut strings had a nodule on one side or were knotted individually by the musician so they could be fastened to the tailpiece. Strings with steel or synthetic cores require a defined end with a ball or loop so they can be fastened into the tailpiece or onto the fine tuner. 


Thomastik-Infeld offers strings with ball ends and loop ends.

Strings with synthetic cores cannot be provided with removable balls.


Depending on the production and requirement, ball ends, crimp ends and tulip ends can be used. Each of these balls is connected to the string core using complex knotting technology. To easier differentiate the strings from one another, Thomastik-Infeld uses different materials to coat the ball ends. This leads to different results in color:
