This instrument shows some signs of weather checking in various spots. The sunburst finish still retains a bit of red hue. It has an authentic vintage presence that cannot be replicated by relic finishes. The sound is well-played in, and thanks to the heavy one-piece ash body, the bass has incredible low-end power. At the same time, the one-piece maple neck provides a bright treble presence, creating a truly characteristic sound of this era’s jazz bass. I purchased this full original vintage Fender USA 1975 Jazz Bass used 12 years ago. This is a very rare full original vintage model from 1975. Please take this opportunity to acquire it. * The one-piece body from this time (1975) is extremely valuable. I have visually inspected the surface and back of the body for any signs of laminating. I have also checked the neck pocket and control cavities in detail, but found no signs of bonding, thus confirming it is a one-piece body. * The pickguard has three screw holes that have been repaired. It looks like the expanded screw holes were filled with resin and polished; the repair is not noticeable from 50 cm away. The two lower screw holes on the body side were also enlarged, so two holes were filled with maple dowels by a professional repairman (this was done after I acquired it). * Body Material: The one-piece ash body and one-piece maple neck were used starting around 1974 for sunburst finishes. The wood grain of this instrument is relatively subtle, showcasing its beautiful appearance. Due to the specific White Ash body from this era, it weighs about 4.67 kg (with pickups and bridge cover removed), making it quite heavy. The black pickguard and the relocated finger rest on the four-string side are characteristics from around 1974. Also, from 1975 onwards, the neck joint changed from the traditional four-bolt design to a three-bolt micro-tilt adjustment joint, which is utilized in this unit. The neck joint has a body date marked "4655." This unit can be identified as being made in 1975 based on the number "4655" which indicates week 46, year 75, and Friday. The date on the neck end is fading, making it hard to discern, but from the number "02034753" it can be inferred from the breakdown: 02 (Jazz Bass), 03 (Maple one-piece neck), and 47 (week 47) 5 (year 75, Wednesday), confirming it was also made in 1975. The headstock features a CBS logo with a patent number, and the tuners are nickel-plated with registered marks. The pickups are gray bobbins with dark enamel wire. The pickup dates are hard to confirm due to adhesive build-up, but the rear pickup can be read as "X85075" and the front is particularly indistinct as "XXXX7X.” The rear is identified as "X8 (manufacturing number) 50 (week) 75 (year 75)." The pot dates are as follows: "137754X" and "1377533" and "1377536". This indicates they were made in 75 (year) during weeks 4, 33, and 36 respectively. All solder joints are identified as original, all made in 75. None of the three controls exhibit any noise. The capacitor is an Illinois Tool Works (ITW) manufactured blue 0.022μ polypropylene capacitor, used in jazz basses since around 1972. The pickup fence and bridge cover are included. However, the thumb rest is missing. The neck shows no warping and maintains almost perfect straightness, with the truss rod still having ample room for adjustment. The action is set to 2.0 mm for the 1st string and 2.3 mm for the 4th string at the 12th fret. The frets show partial wear from when I first purchased it. I have barely played it since I acquired it, and there are no signs of dead spots or buzzing. If you plan to use it heavily, you might consider a refret soon. I have chosen not to modify this vintage bass. I have polished the frets and maintained the fingerboard with lemon oil for this listing, and I have put new Ernie Ball Super Slinky 45-100 strings on it, making it ready for immediate enjoyment. Serial Number: 680629 Includes original black tolex hard case. The under-line Fender logo is known as the "tail logo emblem" and has been used since around 1969. The internal cushioning of the case under the body has been included since around 1973. While there is some rust on the hardware, the handle leather shows minimal deterioration, and there are no locks malfunctioning; it comes with one functional key. Overall, this 70s hard case is in good condition. For the past 10 years, I have kept it stored indoors in a climate-controlled environment using a dehumidifier, hanging it on a guitar hanger rather than in the case. **Bonus:** Includes a black pickguard, black pickup covers, bridge, strap pins, and new screws purchased as Fender Pure Vintage Parts (USA) totaling around 20,000 yen. If you'd like these, please request them as a bonus at the time of purchase. Shipping will be secure with recycled boxes and cushioning material, at my expense throughout Japan, via Express delivery (EAZY). Please contact me with any questions and ensure you are satisfied before bidding. If any serious issues arise, such as no sound, I will respond sincerely, but please keep in mind this is a used musical instrument from an auction. No claim, no return, and no cancellation principles will be strictly followed. Thank you for your understanding.
