I'm thinking about trying my hand at winding some full size bobbin Firebird pickups with alnico 2 magnets for it. I've never done it but it looks to be within the realm of possibility.
There are plenty of regular mini firebird pickups out there but not many people make a full size one so I'm not sure what they would sound like.
Rather than dive into winding my own pickups, I decided to try out something similar and ran across an interesting set for cheap on Reverb. So I took the Classic 57 and 57+ out and put these in. I really like them, they are definitely not a typical Gibson or Fender sound. Other than being full size humbuckers, they are exactly the specs I was looking for. You can't buy them separately and they only come in select models, so I consider myself lucky to have found them so quickly and easily.
These are set of Epiphone Probucker FB720
"Epiphone's ProBucker™ humbucker has quietly become one of the most talked about pickups in the industry. It has fooled experts, vintage purists, and even luthiers who have worked with the best vintage examples from the late 50s and early 60s. Epiphone ProBucker™ humbuckers are the real deal--made with 18% Nickel Silver unit bases and covers, the same alloy used by Gibson at the Kalamazoo factory when the humbucker was first invented. The use of Nickel Silver reduces the occurrence of eddy currents due to low conductivity and provides a more transparent and crisp output. The size and shape of the bobbins also has a great impact on tonal response. And the bobbins used on ProBucker™ pickups duplicate the size and shape of the gold standard in the industry, Gibson humbuckers. Epiphone ProBucker™ pickups also feature sand cast Alnico II magnets, high quality 4 conductor lead wire, and are vacuum wax potted to eliminate microphonics."
"The "Treasure" Firebird-I is powered by the new ProBucker™ FB720 pickup, reconstructed at Epiphone to the original specifications of Gibson Firebird pickups from the mid 60s. Accept no substitutes! The ProBucker™ FB720 has two Alnico II bar magnets used as blades in coils along with a steel reflector plate to achieve the classic Firebird tone of the 60s. Because the DC resistance is around 7.85Kohm, the ProBucker FB720 provides a clean, brighter output with incredible touch sensitivity and a warm low end compared to mini humbuckers, which are used in most Firebird reissues."
