Vintage assembly for Precision Bass. Made with carefully selected vintage capacitors, vintage wiring, and vintage solder. (Inch size is standard, but centimeter conversion is possible.) This is the most popular setup for repairs. Using vintage wiring realistically expresses the improved sound quality achieved with vintage capacitors. Vintage wiring materials, including those used in high-end guitars, have a different level of resolution compared to the wiring materials commonly used in modern guitars. Sounds that were previously vague and muffled in the depths of the speaker will now spread out and jump out at you realistically. You can enjoy the delicate touch of your fingertips, which was previously only vaguely expressed, and the nuances-filled sound. Also, the speed at which the sound comes out after playing is faster, which should have a positive impact on your playing. We have carefully selected numerous vintage wiring materials, choosing those that are close to the tone of modern general bass sounds and that maximize the bass sound. The capacitor is the most popular Bumble Bee among plastic types (the photo shows 200v, but we are currently changing to 400v). Circle D, which was originally used by Fender, is also popular, but this one has a thicker range. Compared to the popular Cornell Tiger, both have a swell, but the contour is sharper and clearer. Capacitors can be changed upon request. Please inquire. Simply solder the included repair vintage solder to your pickups (2 places) and the ground connected to the body (1 place). It's an easy task if you have a soldering iron. Instructions for installation are included. Once you get used to this sound, you won't be able to play other basses because of its amazing sound quality. Vintage capacitors and wiring materials do not result in the old-fashioned sound quality of the past. It simply eliminates the annoying sound range caused by many impurities in modern times, the vague and muffled sound quality that cannot express subtle changes, and the weak, thin sound quality. It allows you to maximize the power of modern, evolved pickups. You cannot achieve this sound even if you use current effects pedals or cables. First-timers will surely be surprised. Please try it out on this occasion. Pots - CTS 250k A curve Jack - Rean
