This circuit upgrade allows for easy improvement of your Japanese-made Stratocaster using CTS pots with metric dimensions. Circuits in Japanese-made guitars often use inexpensive, low-quality components due to cost considerations. Replacing them with a higher-quality circuit will allow you to experience improvements in "sound range, response, and noise reduction." Selector: OAK 5-way Pots: CTS-A250MM x 3 Capacitor: Orange Drop 0.047uf 600v Wiring: Fender cloth wire Jack: Switchcraft Wiring is master volume, front + center tone, and rear tone. Metric size, so it fits most Stratocasters, including Fender Japan models, but you may need to slightly enlarge the selector screw holes on Japanese-made pickguards. If necessary, use a round file to enlarge the holes for installation. The pickguard in the photo is not included. CTS pots in metric sizes are not widely available, so the production of these circuits will be very limited. Inch-size Stratocaster circuits are also available separately. *We also sell various custom circuits, aged parts, etc.
