This is a circuit for a Telecaster that allows for the standard 3-position settings plus a series connection of the front and rear pickups. * The control plate and knobs in the photo are also included. * The quality of the wiring has been improved, and cross-wire is used for the cold wiring. This is not a typical 4-way circuit, but rather a design that adds a push-pull switch. With a 4-way switch, it can be unclear which position you're in while playing, and there's a possibility of selecting the wrong position. However, this circuit adds a push-pull switch to the tone control. When pushed, it functions as a standard 3-position setup, and when pulled, it forces a series connection. For example, you can pull the switch for a solo to get a powerful sound, and push it back in for backing to instantly return to the position you selected before the solo. Cross-wire is used for the wiring. The capacitor is not the standard orange drop, but a beautiful vintage tropical fish capacitor from the 70s-80s. (Orange drop capacitors are also available for an additional 500 yen, including replacement labor.) * Regarding installation: This is a completed circuit, so all you need to do is solder the + and - wires from the pickups, the + and - wires to the jack (approx. 20cm), and the string ground wire connected to the bridge. Detailed wiring instructions will be included with the product, so please rest assured. The photos are reused, but this is a listing for a circuit with the same specifications. Various circuits can be made. Please inquire. We create circuit assemblies for guitars and basses. Special specifications based on various orders are also possible. There may be some minor scratches from the manufacturing process and solder marks from the operational check, but these are newly made, so please understand and be assured. Type...Telecaster type
