A connector is located between the saddle and the underblock allowing the underblock to slide into position on the bridge plate until the connector is tightened, thereby locating the saddle on the sound board. ## Claims ### Claim 1 A sliding saddle system for a chordophone instrument, the instrument having a neck, a soundboard and a soundbox, the sliding saddle system having at least one combination comprising: i) a bridge plate, the bridge plate for connecting to an inner surface of the soundboard; i) a saddle for locating on the soundboard, the saddle comprising an opening for accepting a string and directing it through a slot in the soundboard; iii) an underblock for retaining the string, the underblock in slidable engagement with the bridge plate; and iv) an adjustable connector, for connecting the saddle to the underblock, such that in use, the underblock is slid into position on the bridge plate, and the connector is tightened, thereby locating the saddle on the soundboard. ### Claim 2 (depends on 1) The sliding saddle system of claim 1 wherein there are six combinations. ### Claim 3 (depends on 2) The sliding saddle system of claim 2 further comprising a transducer on the saddle of each combination. ### Claim 4 (depends on 2) The sliding saddle system of claim 2, wherein the bridge plate is a single unit and is wedge-shaped with a taper normal to a longitudinal axis of the saddle. ### Claim 5 A chordophone instrument having a headstock, a neck, a bridge, at least one string and a soundbox, the soundbox comprising sides, a back and a soundboard, the soundboard comprising a soundhole, wherein the improvement comprises a strut, the strut housed in the soundbox and spanning between a distal end of the neck and an end block affixed to the distal end of the soundbox, the strut adjustably connected to the end block to allow adjustment of the strut towards and away from the soundboard, thereby adjusting neck angle and string height. ### Claim 6 (depends on 5) The instrument of claim 5, wherein the instrument is a guitar. ### Claim 7 (depends on 6) The instrument of claim 6 further comprising an at least one slot distal to the soundhole and a sliding saddle system, and the sliding saddle system having at least one combination comprising: i) a bridge plate, the bridge plate connected to an inner surface of the soundboard; i) a saddle slidably located on the soundboard in the vicinity of the slot, the saddle comprising an opening for accepting the string and directing it through the slot in the soundboard; iii) an underblock retaining the string, the underblock in slidable engagement with the bridge plate; and iv) an adjustable connector connecting the saddle to the underblock. ### Claim 8 (depends on 7) The instrument of claim 7, further characterized in that the headstock has an offset. ### Claim 9 (depends on 8) The instrument of claim 8, wherein the headstock is configured to accept six strings, such that two strings terminate in the vicinity of the offset and four strings terminate opposite the offset. ### Claim 10 (depends on 7) The instrument of claim 7, further characterized in that the soundboard and back have integral kerfing units. ### Claim 11 (depends on 7) The instrument of claim 7, further characterized in that the neck has an integral fretboard. ### Claim 12 (depends on 7) The instrument of claim 7, further comprising transducers located on each saddle. ### Claim 13 (depends on 11) The instrument of claim 11, further comprising at least one voice coil and moveable magnet. ### Claim 14 (depends on 11) The instrument of claim 11, further comprising a peripheral toning groove in the soundboard. ### Claim 15 A headstock for a neck of a chordophone instrument, the headstock comprising an offset side and an opposite side and being configured to accept fewer tuning keys on the offset side, such that in use, the strings are parallel to the neck. ### Claim 16 (depends on 15) The headstock of claim 15, wherein the headstock is configured to accept two tuning keys on the offset side and four tuning keys on the opposite side. ### Claim 17 A method of constructing a chordophone instrument, the chordophone instrument comprising a headstock, a neck, a bridge and a soundbox, the soundbox comprising sides, a back and a soundboard, the soundboard comprising a soundhole and at least one slot distal to the soundhole, the method comprising: attaching a bridge plate to an underside of the soundboard in the vicinity of the slot; attaching the back and soundboard to the sides to provide the soundbox having a soundbox aperture; connecting a strut to the neck at a neck distal end; introducing the strut and neck into the soundbox through the soundbox aperture and affixing it therein; locating at least one saddle and underblock about the slot, the underblock located under the bridge plate; and affixing the saddle to the underblock. ### Claim 18 (depends on 17) The method of claim 17 further comprising adjusting the neck angle and string height. ### Claim 19 (depends on 18) The method of claim 18, further comprising adjusting the placement of the saddle and underblock. ### Claim 20 (depends on 19) The method of claim 19, further comprising preparing the soundboard and back with integral kerfing units.
