Do you want the obvious visual and tone improvement of a Faber® bridge on your Epiphone (and many other non USA made) guitar? This is the solution for owners who want the "vintage" look without the need to alter the guitar body in any way. Although not as sustain enhancing as our E-Sert, the ESWKIT with steel posts (8MM base/4MM stud), is a huge improvement over the stock bridge posts/thumbwheels and will easily allow you to the use our ABRM or Tone-Lock bridges. A simple "remove and replace" solution! Comes with one pair STEEL studs and integrated machined brass thumbwheels.
