By replacing the wiring of the output jack with high-quality components, not only is the sound quality improved, but the structure is also more resistant to noise. Passive pickups in guitars and basses are easily affected by wiring and potentiometers. While there are methods to deal with noise, such as noise processing or changing the potentiometer wiring capacitor, the most impactful area is the final output jack. This part strengthens the wiring around the jack, easily improving sound quality and noise resistance. The basic wiring uses Belden, and after much trial and error, it's twisted into a two-conductor configuration. The Belden model number is not disclosed due to the various tests conducted. Also, similar to Gibson, using a large-area mesh wire for the negative side allows noise around the jack to be grounded. The range is wide, and noise is reduced, so it doesn't matter what type of pickup you use. You can use it with vintage-style single coils to humbuckers. The jack is the standard Switchcraft mono jack. Its durability is incomparably higher than domestic jacks. The wiring length is approximately 24 cm. *The photos are reused, but this is a listing for a product with the same specifications. We create circuit assemblies for guitars and basses. Special specifications based on various orders are also possible.
