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

Independent shopping perspective
Gibson Custom’s Custombucker Underwound is an uncovered zebra humbucker built around 42 AWG wire, unbalanced coils, and an unpotted design. Its reduced bobbin windings bring overtone and harmonic detail forward, with a brighter voice when used in the rhythm position. The Alnico III magnet retains the warm, sweet character associated with the Custombucker design. It can be installed in any position, though its rhythm-role voicing is specifically suited to pairing with a standard Custombucker at the treble position.
