Firelfy is a humbucker that definitely has the grain of old Slavic legends in it. Although at first glance it seems to be an extremely aggressive humbucker, it has many subtleties that can easily lead you astray.
The mids are scooped, the hi end exposed and glassy. Sometimes you might get the impression that it sounds similar to powerful single-coil pickups or strat-type mini humbuckers.
Due to the design and asymmetrical coils of pickup, the direction of its installation/position of the north and south coils has a great impact on the final sound of this humbucker.
Blade coil creates very equal magnetic field across the strings, which you can experience especially during big bends and solos.
