3.2.2. In the neutral state, the design of the new classic guitar is as follows. Seven strings are set on the main neck 1, six are tuned like a regular six-string guitar, and the seventh is in tone for a counter-octave. The scale of the main neck is 650 mm. The fretboard has 24 frets; the thickness of the main fretboard from the first fret to the fifth fret is unchanged. This is necessary for the normal operation of the moving capo. When installing a removable continuation 8 on the main neck, the number of frets on the main neck increases to 36.

The removable extension of the neck 8 is mounted on two pins tightly glued into it and inserted into the holes on the end of the main neck 1 and the side of the headrest 6. An additional neck 2 is attached to the main neck with an additional bass string tuned in tones kontroktavy.

The additional neck plane is 1.5 mm below the main plane.

Mensura 700 mm, 12 frets are located on the neck.

An additional neck bar 3 is glued to the head of the additional neck 2 and additionally fixed with a metal pin. A sleeve with thread is glued to the head of the main neck 1, to which an additional neck bar is fastened with a screw. In the main neck at a level between 11 and 12, a hole is drilled into which a self-tapping screw is screwed, fastening the main and additional neck in the lower part. The necessary distance between the main bar and the additional bar is provided by a bar stop 5, glued to the additional bar in the place of its attachment to the main screw-screw. The bass string is attached to button 4 and rests on a stand, like with bowed instruments. Subheading 6 starts from the 12th fret of the main neck. The plane of the fenders is 3 mm below the plane of the main neck. The size of the headplate is 320 mm, the number of frets is 24. The difference in the height of the planes of the main neck and the headboard provides the position of the additional string 5-6 mm below the main row of strings. The string mounted on the sub-band is tuned a quart higher than the first, pressed at the twelfth fret, to the tone of the second octave. On the stand, the string is attached using the button 7. Next, the upper nut of the head plate of the high-range string passes through the groove 11, being held in it by stops 12 up to the upper nut of the main neck and the splice. The planes of the main neck and the subrigit are not parallel to the deck, but form an angle of about 1-2 degrees with respect to it.

Stand 9 is mounted on the guitar body using spring clips.

The holder of the lever 29 is attached to the stand 9. It is attached to the guitar body by a screw screwing into the sleeve fixed in the lower glue of the guitar body.

The guitar lies on the left foot of the performer, leaning on it with a stand 9.

The foot stop 27 is located on the right foot of the performer.

The emphasis with suction cups 10 creates a gap between the body of the performer and the lower deck of the guitar, necessary for the normal operation of the moving parts of the moving capo switch.

The left leg is located with the heel on the stop 33 of the remote fixation of the movable capo. The movable capo 15 is located on the end stop 13.

3.2.3. The geometric shape and dimensions of the components of a movable remotely controlled device for pressing strings are selected depending on the geometric shape and dimensions of the guitar neck, and the following requirements must be met:

- in the neutral position of the device and when moving the clamping frame 20, in a position where the strings are pressed by the finger of the performer to the fingerboard, it does not touch the strings;

- in the on position of the device, the clamping frame 20 tightly presses the strings to the fret;

- in the off position of the device, the return spring of the frame 21 returns it to a neutral state;

- when transporting a new classical guitar, all the structural elements of the movable capo switch 16, the remote fixation panel for the movable capo 17, stand 9, emphasis with suction cups 10 are removed from the instrument.

3.2.4. The components of a mobile remotely controlled device for pressing strings are made of the following materials:

Frame return spring 21, pressure lever return spring 24, pressure lever return spring 35 from spring steel. Tensioner 22 made of rubber band. The slide bearing of the carriage 19, the guide rods of the shifter 14 and 26, the guide of the tensioner 22 from ftoroplasta. The lever 28 and the connecting pin 30 are made of plastic.
