Kramer Guitars have primarily used Gibson, Schaller, Seymour Duncan or Kramer pickups. DiMarzio pickups may be directly swapped-in for the factory pickups in a Kramer Guitar. Kramer guitar models use simple control schemes that only require replacing two wires to change the pickup. The only significant difference between DiMarzio pickups and the stock pickups is the wire coloring. This applies to both humbucker and single-coil pickups.
Plug the soldering iron in. It takes a few minutes for the soldering iron to warm up enough to be used.
Touch the ends of the white and black wires together.
Touch the tip of the soldering iron to the electric solder to melt a drop on the tip.
Touch the drop of solder to the ends of the white and black wires. The solder solidifies to hold the wires together once the heat from the soldering iron is removed.
Wrap the soldered ends of the white and black wires with electrical tape.
Touch the end of the soldering iron to the two spots the Kramer factory pickup wires are connected to on the guitar controls. Remember the two locations where the old pickup was connected. The wire connected to the back of a control is the ground wire. The other wire is the hot wire.
Solder the red wire of the DiMarzio pickup to where the hot wire was connected.
Solder the green and bare wire to where the ground wire was connected.
