Poly-coated pickup coil wire is the modern standard: consistent coating gives a cleaner, more uniform sound in similar pickups with the same number of windings. "On most pickups, I use poly-coated coil wire for its consistency, durability and overall clear sound." —Erick Coleman, repairman and StewMac tech advisor Each 1/2-pound roll has over 25,000 feet of wire, enough to wind 5-6 single-coil pickups, or 2-3 humbuckers. 43 AWG (American Wire Gauge) is used at the Tele® neck position and in Rickenbacker pickups. 43-gauge wire requires fewer windings to attain a desired coil resistance.
