Introducing the Epiphone Genuine ProBucker mini Humbucker Set. Similar to the FB720, which has no pole pieces, these humbucker pickups are made in the mini-humbucker style with ProBucker specifications. The nickel cover gives it a vintage feel, and the adjustable pole pieces allow for volume adjustment of each string. These are authentically made using Alnico magnets, not the typical ceramic magnets. The lead wires also use braided wire, making them comparable to genuine Gibson mini-humbuckers. Output is approximately 6.4k for the neck and 7.8k for the bridge. Lead wire length is approximately 320mm for the neck and 260mm for the bridge. Nickel cover size: Width: 68mm, Height: 28mm, Depth: 15.7mm (excluding base plate feet) The pole piece pitch is 49.2 mm (center to center from the 1st to 6th string) for both the neck and bridge, which is Gibson pitch. The screws are metric. This set includes elevation screws and mounting screws. They can be directly inserted into the body with screws or used by inserting them into a dedicated stay. Please note that they are completely different from P-90s and are not compatible. Protective seals for the top surface come in two types: with text and transparent without text. Which one is shipped depends on the stock availability, so please understand. If you want them with an escutcheon, they are listed separately.
