The old firebird pickup is very different to most "normal" humbuckers, and actually uses a pair of bar magnets in place of any steel poles, so we carry a kit to rebuild or repair that style of pickup.

Closed faced Mini humbuckers are associated with one guitar usually - the Gibson® Firebird! They actually turn up on a few other makes and models, but its the Firebird® we all think of when we see this style of cover/pickup.

The pickups in that guitar, originally, were actually a bit of a departure from what had been before - rather then using a bar magnet and steel poles (either poke screws and slug, ala a "normal HB", Pole Screws and steel bars, ala a "traditional mini HB" or even the modern Firebird offerings, which simply use 2 steel bars!) the real deal Firebird® Mini humbucker used 2 bar magnets, slotted into the housings on the bobbins.

Base for traditional style mini humbuckers, but with 12 pole screws - not to be confused with Filtertron® size pickups, the mini humbucker normally turns up on Gibson® and Epiphone guitars, and is considerably smaller then a normal humbucker.

These are the bar magnets commonly found in Gibson® firebird mini humbuckers - used as a magnetic pole within the bobbin, resulting in a very different tone.

These Mini Humbucker Base Plates come in a choice of Nickel or Brass.

These are the "traditional" Mini humbucker bobbins - weirdly, a lot more generalized then normal humbucker bobbins, allowing for much more customisation on the construction of the pickup, but ultimately, forcing you to always have a cover on a Min-bucker.

This is the "reflector plate" that sits on top of the bobbins on a mini
humbucker which has bar magnet poles, as seen on the Gibson® Firebird.
