My version of the Silvertone 1446 “Isaak” pickup that Gibson made for Silvertone, and Epiphone.   I recently took a ground up retooling of this pickup.  I choose to stay with the modern Mini Humbucker size rather than vintage as that is the most common size for these days.  I had all new  covers, base plates, steel bars and pole pieces designed for this pickup.  Best of all is I had the ring recreated.  For those that know, the vintage ring did not fit the modern sized covers.  I made this ring to fit the modern cover yet have the SAME exact footprint as the vintage.  Rings are injection molded using high quality ABS plastic.  All this tooling cost a small fortune and will likely never pay off, but was a needed recreation.
