Abstract: A textured surface for improving grip on plectra and other hand-held implements. A series of parallel ridges serve to frictionally engage thumb and forefinger surfaces and “lock” the grip in place.

Abstract: A machine for placement on the fingertips of players of stringed instruments with which the strings will picked or plucked. Designed as a set, the two picks do not collide as the musician moves his or her fingers to pick the stringed instrument, The abrasion of the interior of the picks, prevents pick slippage, even when worn comfortably loose, The forefinger pick is designed with a unique diagonal wrap that may be adjusted to fit a range of finger sizes, The middle finger pick is designed with wings that provide a gap which allows the adjacent pick to touch the skin of the middle finger instead of allowing metal to touch metal, The forefinger wrap is placed to avoid the metal of the middle finger pick and instead touch the skin of the middle finger, and The shank (the tip portion) may be adjusted or bent to the conformation desired by any given musician.

Abstract: A capo device for a stringed instrument for quickly and effectively clamping strings to the fingerboard of a stringed instrument. The capo device for a stringed instrument includes a frame capable of extending about a fingerboard of a stringed instrument; and also includes an assembly for clamping strings to the fingerboard of the stringed instrument; all features not described nor suggested by the prior art.

Abstract: Finger-controlled members for contacting the strings on a guitar includes three string-contacting finger members, one for the index finger, one for the middle or second finger, and one for the third or ring finger. Each of the string-contacting finger members is securely fastenable upon the respective finger such that it is on the palm-side of the finger and on the second segment of the finger so that the user can manipulate the string-contacting finger members with one's finger tips. Each string-contacting finger member has a body with a single string contact stem extending from the bottom thereof and being capable of holding only one string against the fingerboard of the guitar. In addition, there are four multiple string contact attachments which can be detachably attached to the string-contacting finger members and which have bottoms that are capable of holding two or three consecutive strings or two nonconsecutive strings against the fingerboard of the guitar to achieve selected musical chords.

Abstract: An inventive positioner adapted to secure a string of a guitar or other fretted stringed instrument at fret positions in order to quickly and easily vary the length of the string available for vibration to change the pitch when the string is plucked. The positioner describes a threaded machine screw received in a metal insert, the insert fixedly held in the fretboard of the neck of the guitar. The positioner screw is angled at a preferred 55.degree. angle with respect to the fretboard and so positioned that it hooks the string in a locking downward "V" catch to secure holding the string against the fretboard so that the string will rise up and engage the adjacent fret between the positioner and the guitar main body. The guitar string is not moved laterally when it is engaged and held.A plurality of positioners are provided for each of the guitar strings behind each fret throughout the length of the fretboard in order that each guitar string effective vibrating length may be changed as desired.
