摘要： A hand powder composition, particularly useful for musicians of necked stringed instruments, comprising a fine moisture absorbing powder in an amount from about 90%-99% by weight of the total composition and a fine polytetrafluoroethylene powder in an amount from about 1%-7% by weight of the total composition. The polytetrafluoroethylene powder may have average particle sizes of about 18-22 μm. The moisture absorbing powder may be talcum powder or corn starch, or a combination thereof. A fine alkaline powder may be included to neutralize acidity of perspiration. A fine powdered colorant may be included for approximately matching the color of the composition to a desired color.

摘要： Devices and methods for mounting a tuning machine with locator pins to a stringed instrument having a mounting configuration with receiving holes that are misaligned with the tuning machines locator pins. A mounting element is provided having top and bottom surfaces and a post aperture to receive the tuning machine's post. Tuning machine alignment apertures in the top surface are in alignment with and adapted to receive the locator pins when the post is located within the post aperture, and instrument alignment elements in the bottom surface are in alignment with the receiving holes on the instrument when the post is located within the post aperture on the mounting element and the first post aperture on the instrument. The top surface complementarily receives the base of the tuning machine, and the bottom surface complementarily fits with the mounting configuration of the instrument such that the tuning machine can be secured to the mismatched instrument.

摘要： Improved pickups for stringed instruments, such as guitars, ukuleles, banjos and the like. The pickup system includes a housing with a transducer element and a first magnetic means, and a distinct second magnetic means that cooperates with the first magnetic means to grasp a part of the instrument there between and thereby releasably mount the pickup on the instrument. Thus the pickup system can be easily mounted, removed or moved to other locations on the stringed instrument to produce the most desirable effect.

摘要： A saddle for a stringed instrument comprising an elongate member having a string support surface for supporting strings of the instrument and a base for connecting to the stringed instrument. The elongate member has at least one internal cavity and an insert made from a resonant material is received in the internal cavity. The insert may be formed from a material having the same or a different density than the material of the elongate member. At least one piezo electric crystal is embedded in the insert to faithfully and reliable capture the vibrational energy of the strings. The saddle provides a compact and simple apparatus for reliably and accurately amplifying the sound of a guitar, particularly an acoustic guitar. The piezo-electric crystal relies on vibration of the strings to generate a signal, but not on downward pressure as with conventional under the saddle pickups. Optimum string balance with the saddle is much easier to achieve as each string does not have to be adjusted over an associated piezo-electric crystal.
摘要翻译：一种用于弦乐器的鞍座，包括具有用于支撑琴弦的弦支撑表面的细长构件和用于连接到弦乐器的底座。细长构件具有至少一个内部空腔，并且由共振材料制成的插入件容纳在内部空腔中。插入件可以由具有与细长构件的材料相同或不同的密度的材料形成。至少一个压电晶体嵌入到插件中，以忠实可靠地捕获弦的振动能量。鞍座提供了一种紧凑简单的设备，用于可靠且准确地放大吉他，特别是吉他的声音。压电晶体依赖于弦的振动以产生信号，而不是如在传统的鞍式拾音器下方的向下的压力。与鞍座的最佳弦平衡更容易实现，因为每个弦不必在相关的压电晶体上进行调整。

摘要： A plectrum for striking a stringed instrument is planar so as to define a first side and a second side opposite the first side. The plectrum has a wide end a narrow end opposite the wide end. The plectrum includes: (a) a gripping portion disposed at the wide end, the gripping portion having a first thickness and a first flex; and (b) a thicker portion disposed at the narrow end, the thicker portion having a second thickness that is at least 10% greater than the first thickness and having a second flex that is less than the first flex, the plectrum defining a tip having a thickness greater than the first thickness.

摘要： A wraparound bridge or tailpiece for a stringed musical instrument such as guitar, banjo, and the like, comprising an elongate body having top and bottom surfaces, and front and back edges, and a mounting means for mounting to the instrument such that the bottom surface faces the instrument and the front edge faces the neck of the instrument, and a plurality of string channels defined in the bottom surface, each string channel extending from the front edge toward the back edge and including a narrow portion open to the bottom surface to receive a string and a wider front cavity open on the front edge to receive and capture the ball end of the string. Hence the end of a string with the ball end may be slid underneath the body in a fore direction and once the ball end clears the front the string may be moved upwards until it is received within the string channel, and then drawn rearwards until the ball end abuts the narrow portion of the string channel.
