The EM4 Fender-style Ring makes it easy to mount any of our Universal Mount pickups to your Fender-style instrument. This ring has the same dimensions as the EM1 ring but is made of flat 1/8 inch black plastic instead. Fits Filter'Trons, not standard Humbuckers. Comes with one ring and four screws.
Note: Original Gretsch Filter'Trons and TV Jones Filter'Trons have a clean 1/4 inch corner radius. Some modern Gretsch Filter'Trons are made with more square-like corners and may not fit this ring.
