This document outlines the components and associated part numbers for the American Deluxe Jazz Bass FMT 0195870/72, providing a comprehensive guide for assembly, repair, and customization. The instrument is designed for musicians seeking a high-quality bass with advanced features and a refined aesthetic. Its construction emphasizes both playability and tonal versatility, making it suitable for a wide range of musical genres and performance settings.
The core of the bass's playability lies in its neck, available in two configurations: American Jazz Bass, R/W (Rosewood) and American Jazz Bass, M/N (Maple/Nut). These options cater to different tactile preferences and tonal characteristics, allowing players to choose the feel and sound that best suits their style. The neck is securely attached to the body, ensuring stability and optimal vibration transfer. Tuning is managed by a set of tuning keys, which are crucial for maintaining accurate pitch. These keys are designed for smooth operation and reliable tuning stability, even during vigorous playing.
At the headstock, a bone nut provides a solid foundation for the strings, contributing to sustain and clear articulation. String retainers are also present, helping to guide the strings properly and maintain consistent tension, which is vital for tuning stability and preventing string slippage. Mounting screws are used to secure these components, ensuring they remain firmly in place during use.
The instrument's truss rod adjustment nut and truss rod adjusting wrench are essential for maintaining the neck's relief. The truss rod allows for precise adjustments to counteract string tension and environmental changes, ensuring the neck remains straight and the action (string height) is optimal. Regular truss rod adjustments are a key aspect of bass maintenance, allowing players to fine-tune the instrument's setup for comfortable playing and consistent tone.
The body of the American Deluxe Jazz Bass is crafted from alder and finished with a paint, contributing significantly to its resonant qualities and visual appeal. The "xxx" in the part number for the body indicates various color options, which are further detailed in the "Body Part Number" section. These color options include Aged Cherry Sunburst, Amber, Crimson Transparent, and Tobacco Burst, offering a range of aesthetic choices to suit individual tastes. The neck plate, secured by mounting screws, provides a stable connection between the neck and body, enhancing sustain and structural integrity.
Strap buttons are provided for attaching a guitar strap, allowing the instrument to be played comfortably while standing. These buttons are typically robust and designed to withstand the rigors of live performance. Felt washers, in both black and white, are used with the strap buttons and other components to protect the finish of the instrument and prevent metal-on-metal contact.
The bass features a sophisticated pickup system, with separate pickups for the neck and bridge positions. These Deluxe Jazz Bass pickups are designed to capture the instrument's full tonal range, offering a rich and articulate sound. Each pickup is secured by mounting screws and includes a cover with a logo, adding to the instrument's aesthetic. Weatherstrip rubber is used with the pickup covers, likely to provide a snug fit and reduce unwanted vibrations. The distinction between "Weatherstrip, Rubber" and "Weatherstrip, Rubbber" might be a typographical error, but both serve the same protective and dampening function.
The electronic heart of the bass is its printed circuit board assembly, which houses the various controls. These controls include a 25KB audio control, a 100KB Tocos CN DTNT control, a 100KB CNTR CTS control, and a 250K Pan Alpha control. These potentiometers allow players to shape their tone by adjusting volume, blend, and equalization settings. Mounting hex nuts, lock washers, and flat washers are used to secure these controls to the instrument's body, ensuring a stable and reliable electrical connection. The variety of control types suggests a versatile active electronics system, offering a wide range of tonal possibilities.
The instrument's output jack is where the bass connects to an amplifier or other audio equipment. It is secured by a mounting hex nut, lock washer, and flat washer, ensuring a robust and reliable connection. Ferrule jacks and mounting screws are also used in this area, contributing to the overall stability of the output system. Solder lugs and mounting screws are provided for internal wiring connections, indicating that the electronics are designed for secure and professional installation.
Knobs are an integral part of the control system, allowing players to easily adjust settings. The American Deluxe Jazz Bass features various types of knurled gold knobs: lower, upper, small, and Burton. These knobs are secured by set screws, ensuring they remain firmly attached to the potentiometer shafts. The gold finish adds a touch of elegance to the instrument's appearance.
The bridge assembly is a critical component for string stability, intonation, and sustain. It includes a bridge plate, bridge sections (1&2 and 3&4), intonation screws, and intonation springs. The intonation screws and springs allow for precise adjustment of each string's length, ensuring accurate intonation across the fretboard. Height adjustment screws and an adjusting wrench for saddle height are also provided, enabling players to fine-tune the string action for optimal playability. Ferrules for string retainers are part of the bridge system, ensuring the strings are securely anchored.
For instruments with active electronics, a battery cover is included to house the 9-volt battery that powers the system. Mounting screws are used to secure the battery cover, and insertting screws are also listed, likely for internal battery compartment components. The inclusion of a 9-volt battery indicates an active preamp, which typically offers higher output, a wider frequency response, and more versatile tone-shaping capabilities compared to passive systems.
Maintenance of the American Deluxe Jazz Bass involves several key areas. Regular cleaning of the body, neck, and hardware is essential to preserve its finish and functionality. The truss rod should be adjusted periodically to maintain proper neck relief, especially with changes in humidity or string gauge. The tuning keys and bridge components should be checked for wear and tear, and any loose screws should be tightened. The electronics, including the potentiometers and output jack, should be inspected for proper operation, and the 9-volt battery should be replaced as needed to ensure consistent performance of the active system. The felt washers play a role in protecting the finish, and their condition should be monitored during maintenance.
In summary, the American Deluxe Jazz Bass FMT 0195870/72 is a meticulously designed instrument with a focus on high-quality components and versatile performance. Its features, from the choice of neck materials to the sophisticated active electronics and adjustable bridge system, are all geared towards providing a superior playing experience. Regular maintenance, including neck adjustments, hardware checks, and battery replacement, will ensure the instrument continues to perform at its best for years to come.
