Patent number: 9812098Abstract: A musical instrument string covalently and/or ionically bonded with a nano-polymer substance. The nano-polymer substance can be hydrophobic and/or oleophobic, such that it can substantially repel water and/or oils and thereby prevent corrosion, oxidation, and/or other degradation of the musical instrument string. The bonding of the nano-polymer substance to the musical instrument string can also improve the musical instrument string's tone.Type: GrantFiled: August 27, 2015Date of Patent: November 7, 2017Assignee: Dunlop Manufacturing, Inc.Inventors: Bryan Hartley, Theresa Lambert, Jasmin Powell

Publication number: 20040261600Abstract: A C-clamp capo comprises a string press for clamping down on the strings of a string-instrument against a front side of a fretboard. An extension arm curves behind and has an idler clamp with a first pivot attachment. Such enables a clamping action against a backside of the fretboard. A continuous insert having a positioning bumper that ensures consistent positioning against the fretboard is disposed all along an inside surface of the string press from a distal end across the first pivot attachment bridging over to an inside surface of the idler clamp and out to its distal end. A locking lever has a second pivot attachment to the extension arm behind the first pivot attachment, and provides a locking action against a backside of the idler clamp. A setscrew disposed in the locking lever provides an adjustable locking action between the idler clamp and the locking lever, e.g., for a range of thicknesses of the fretboard to be accommodated.Type: ApplicationFiled: June 26, 2003Publication date: December 30, 2004Applicant: Dunlop Manufacturing, Inc.Inventor: Lowell Thomas Silva

Patent number: 6626335Abstract: A guitar shoulder strap incorporates thickened, rolled edges along the length of the strap. The strap webbing between is generally about two millimeters thick and fifty millimeters wide. The thick, rolled edges are almost four millimeters thick and about six millimeters wide. A decorative pattern is weaved into the outside decorative surface. The strap webbing and thick, rolled edges are a single weave of textile wherein many longitudinal fibers have been bunched into cords at the edges and spiraling transverse fibers are woven to build the webbing and encase the cords.Type: GrantFiled: August 20, 2001Date of Patent: September 30, 2003Assignee: Dunlop Manufacturing, Inc.Inventor: James Andrew Dunlop

Patent number: 6545206Abstract: A guitar bridge-pin removal tool has a solid body sized to fit in a users hand and opposite surfaces that can be gripped between the thumb and fingers. A channel is disposed across one end of the solid body. Such channel has a main cross section that approximates that of a head of a bridge pin that retains a string in a guitar. A necked outer edge runs along the longitudinal lips of the channel and captures the head of said bridge pin along any portion. At least one side end in the channel is open to allow the head of the bridge pins to be slipped in and out.Type: GrantFiled: January 10, 2002Date of Patent: April 8, 2003Assignee: Dunlop Manufacturing, Inc.Inventor: John W. Brady

Patent number: 5274710Abstract: A variable impedance device which is connected between the preamplifier of a microphone or electric instrument and a public address system for controlling the signal volume of a musical performance. The variable resistor is controlled by a foot pedal operated by the performer so that his hands are free for an uninterrupted performance. The impedance includes a first section that can be preset manually to provide maximum desired signal volume with the footpedal in one direction (toe depressed on the pedal) and a second section that can be preset to provide minimum desired signal volume (heel depressed on the pedal).Type: GrantFiled: November 26, 1991Date of Patent: December 28, 1993Assignee: Dunlop Manufacturing, Inc.Inventors: Mark S. Shaffer, Samuel J. McRae
