This is a Dimarzio Paf Pro with a genuine Dimarzio nickel cover and nickel pole pieces. It has been potted, and the inner pole pieces have been passed through from the back, allowing for output adjustment from that side as well (it is outputting normally). This is one of several Dimarzio hex pole piece models that I modified in a similar way and installed in an SSH-type Stratocaster, but ultimately didn't use. It was modified from a new condition, so there are almost no noticeable scratches on the surface. Output adjustment can be done without ruining the appearance with the hex pole pieces on the back, so it is recommended for SSH-type guitars. A hex pole piece adjustment wrench, screws, and springs are included.
