The size of wire, the insulation used on the wire, and the number of turns on the bobbin are all important in determining the pickup’s overall tone. Generally, the thickness of a wire around the pickup bobbin is measured in gauges somewhere between 41 to 44 awg in thickness (but we have wire gauges that go all the way from 45 to 20). This wire has a coating on it (insulation) made of any number of materials, from Teflon to certain kinds of plastic. Wire is usually made of copper, but sometimes silver is used. Silver wire extends the dynamics and definition of the notes, but it is also much more expensive. Between selecting size, insulation type, number of turns, and wire material, there are endless combinations. Fortunately the Custom Shop can help you navigate which combinations will work for the sound you are after.
