No, our Auto Lock Straps do not work with acoustic end pin jacks. Auto lock straps are designed to work on most standard-size strap buttons without jacks.
It is possible that a Cinchfit would work, depending on the style of end pin jack on your instrument. These can be used on any standard strap, and are designed specifically for use with end pin jacks. We make two different types of Cinch Fits—one for Fishman/Switchcraft style jacks and one for Taylor Expression Systems.
