This is a Fender Custom Shop Jazz Bass. It's a 1962 model, but with a rare ash body and rosewood fingerboard configuration. It has that classic Fender sound that you recognize immediately, but as you'd expect from a Custom Shop instrument, it produces a remarkably deep tone. The control over sound on and off is exceptional; I don't think there are many instruments that respond so faithfully to finger movements. It reacts not only to picking but also to the pressure of your fretting fingers, which greatly expands the range of nuance you can achieve. Also, the neck seems very rigid, and the feel is completely different from other basses. I own several Fender Custom Shop basses, but I think this is a characteristic of this particular bass, not just because it's a CS model. Perhaps because of this, the body vibrates quite a bit with just a light picking, and the vibrations are transmitted all the way to my insides (I hold the bass above my stomach). Thanks to the ash body and rosewood fingerboard configuration, the sound has a certain allure that you don't get with a maple fingerboard, while also cleverly minimizing the undesirable aspects of the mid-range frequencies often associated with rosewood fingerboards (in my opinion). The sunburst finish really shines on an ash body. The distinctive grain patterns that appear in the common color scheme are a subtle yet noticeable touch of style. It has the early logo. The early logo period predates the start of the Master Builder system, so it represents the highest grade. It's said that the quality is higher than current models because more luxurious wood could be used than today, and because craftsmen made each instrument one by one, just like the current Master Builder models. From my own experience, I feel that the neck is particularly reliable and the sound has a certain "weight" to it.
