  • Patent number: 4867032
    Abstract: The invention is an improvement in thumb picks for stringed musical instruments whereby the pick is self secured to the thumb and can be utilized in both the upstroke and downstroke without the aid of any other finger. The pick consists of an oval shaped band formed to match the shape of a user's thumb and which applies a compressive force upon the thumb. A picking tip traverses at the bottom of said pick at an attitude approximately perpendicular to the instrument strings. A tip support element cooperates with said tip by providing additional strength thereto. An open section of said band permits flexibility thereof and is positioned to prevent a string from accidently catching itself therein.

  • Patent number: 4790227
    Abstract: The invention is an improvement in picks for stringed instruments whereby the pick has multiple edges which displace the string of the instrument by multiple impacts for each stroke thereof. The multiple impacts result in a revibration of the string which increases the harmonic content of the produced sound and creates a sound which is unique and different from that of a standard pick. The sound has a higher treble, is clearer with higher overtones, and provides a higher pitch than picks of the prior art. The pick consists of a center element central between two outer elements with the center element slightly longer than the outer elements, thereby giving the pick multiple edges. This arrangement permits the pick to be equally functional in both the upstroke and the downstroke.

  • Patent number: 4625615
    Abstract: The invention is an improvement in picks for stringed instruments which allows the user to firmly grip the pick for long periods of time without the customary fatigue associated with typical picks of today. Due to its unique construction, the improved pick is stronger and is securely storeable within the instrument's strings, thereby allowing longer usage of each pick. The pick is of the standard size and shape in use today except for the improvement thereon which is a singular raised portion on one surface and a complementary depression of the other surface. The user's forefinger lies within the depression and the thumb lies perpendicular across the raised portion for a firm, secure and comfortable grip.
