Detail 01
42 AWG wire with unbalanced, unpotted coils
Keeps the construction approach described for the historically styled Custombucker design.

Independent shopping perspective
The double-black Custombucker Underwound brings Gibson Custom’s 42 AWG, unbalanced-coil, unpotted humbucker approach into a reduced-wind design. Fewer bobbin windings make overtones and harmonics more clearly defined, while the rhythm position takes on a brighter character. An Alnico III magnet supplies the warm, sweet voice identified with the Custombucker design. Listed for any position, it has a particularly clear role in a two-pickup setup alongside a standard Custombucker in the treble position.
