I saw this news over at Guitar World’s website, Bare Knuckle haven’t even updated their website with this news yet but I expect this will be rectified soon. Guitar World had this explanation of the new humbucker:
Each coil of the humbucker has a pair of annealed nickel-plated steel blades for even transfer of magnetism toward the strings to guarantee perfect string-to-string balance across the width of the pickup.
As per all Bare Knuckles, the coils are scatter-wound by hand and then powered by a trio of custom calibrated magnets. This combination of coil design, winding technique and magnets ensure the Black Hawk humbuckers remain extremely reactive to pick dynamics and responsive to subtle changes of the volume pot.
They also say that the Black Hawk offers the transparency and output of an active with the character and wide dynamic control of a passive pickup, this seems to be a bit of a trend at the moment as there have been a couple of signature pickups by other companies released recently that offer similar claims.
