| 20140083275 | Reverse Bridge Tension Configuration for a Stringed Instrument - A reverse bridge tension configuration for a stringed instrument allows the stringed instrument to offset some of the tension felt by the bridge. For a typical stringed instrument such as a guitar, the tensioned strings are bound between the bridge and the headstock. However, the reverse bridge tension configuration loops the tensioned strings on a path that goes around the back of the instrument, through the body of the instrument, and back to the bridge. A reverse bridge is positioned on the corner of the soundboard and the back end so that the tensioned strings can loop around the back end without causing pressure damage to the outer surface of the instrument. Once the tensioned strings travel around the reverse bridge and into the body, channels are positioned within the body in order to guide the tensioned strings back to the bridge. | 03-27-2014 |

| 20150135930 | METHOD FOR MAKING LIGHT AND STIFF PANELS AND STRUCTURES USING NATURAL FIBER COMPOSITES - Method for making light and stiff panels and structures using natural fiber composites. An improved composite material utilized in musical instruments. Bio-based industrial fiber such as flax, cellulose, hemp, bamboo, and jute combined with a core material such as foam, aramid honeycomb, carbon fiber or balsa wood, and a resin, serves as a replacement to traditional tone wood. In another embodiment, the bio-based composite has no core material but simply layers of fabric with resin. Another embodiment finds layers of the woven bio-composite as the core between outside layers of carbon fiber or aramid. In the case of a string instrument, bio-composites can be used to make a substantially hollow unitary body, neck and head as well as soundboard. Another usage is for the bracing material of the soundboard. In fact in its various forms, bio-composite can effectively replace all the old growth wood currently used. | 05-21-2015 |
| 20160104465 | LOW-FRICTION BRIDGE FOR STRINGED INSTRUMENT - A low-friction bridge for a stringed musical instrument employs a roller saddle that is adapted and positioned to roll upon a race. The race includes structure to guide the roller saddle as it rolls. A musical string is seated in a circumferential groove/saddle formed in the roller saddle. As the musical string stretches or contracts the saddle rolls, and thus the musical string does not slide in the saddle. As such sliding friction is avoided in favor of rolling friction of the roller saddle rolling upon the race. One or more contact members can be biased into contact with side faces of the roller saddle. | 04-14-2016 |
