Re: Pickup's cable thickness
Yes. Even for the tiny wire that is used to wind pickups, the signal generated is far from the maximum voltage or current that such wire could handle.
Wire changes depend on the supplier. Pickup hookup wire is not designed nor made for pickups. It is a commonly made wire used for generic wiring in houses/security systems/irrigation controllers and the like. The minute changes are utterly inconsequential and any 4+shield cable will do.
