Concept and construction
ROTATOR is the name of this new and innovative instrument. The different models of the ROTATOR all have a stationary back part, that can be carried with a normal guitar strap.
The front part consists basically of 2 necks, with neck-thru construction, pointing in opposite directions, and fixed together in each end with 1 piece of milled out brass, which contains both nut, 3D-bridge, tuning system, string fixing, potentiometers, electronics, compartment for a 9 v battery, plus nuts for adjustment of 2 trussrods in each neck.
And a full-size zero-fret with a capo/muting device…
The necks are also fastened to each other exactly in the middle, with a pivot system connected to the back part. Incorporated in the pivot system there is stereo transmission of the signals from the pickups and the electronic in each end of the front part – to 2 mono jack sockets in the back part, in which you plug cables to an amp.
How to use the ROTATOR
By turning the front part 180 degrees you can quickly bring either one or the other neck up to normal playing position, so it can be played as you use to. The normally topmost and most used area on the other neck, that points in the opposite direction, is then where the right hand will be, and the strings are in a good position for tapping some basic bass notes with the fingers on your right hand – or just the thumb, while the other fingers are plucking and picking the strings on the neck, which is played the normal way. Now the fingers on your left hand are more free to play melody lines, solos and chords. The front part clicks in place, in playing position after each rotation.
Our first model on the market is a short scale 4-string, fretted /4-string, fretless bas. The special construction and chosen material creates a bigger tone, than you would normally find on a short scale.
When you play on both fretboards at the same time, the intonation on the fretless fretboard becomes easier, because you can play ”fixed” notes on the fretted fretboard. Because most bass players play fretted bass, they will probably play it in the normal playing position. This instrument is a good introduction to the fretless bass, because of the fact that you can tap some notes with your right thumb and easier tie notes together on the fretless bass by sliding your thumb up and down on the strings.
The model is tuned one semitone down compared to standard and has a 0th fret in normal size. A moveable capo/muting device on 0th fret has more functions, it can be placed in different positions, and is essential for the overall functionality of the instrument:
1: When positioned closest to the nut, and adjusted a bit down, so the strings are dampened, then tapping sounds better, and the strings don’t vibrate, when you play on the other neck. The 0th fret is easy to use, and then the notes EADG doesn’t work as open strings, but are played by pressing down in the 0th fret after the capo/muting device.
2: Mid position: Here the capo/mutingdevice can also be used to dampen to the strings, and there is still space to play in the 0th fret. By adjusting all the way down it can also be used as a capo, and then EADG work as open strings, like on a normal bass. Here it is recommended, that the strings on the other fretboard are dampened.
3: The 3rd position, approximately in the middle between the frets is mostly used, when it should work as a capo, and it also ensures a low string action.
All the necks are made in 1 whole piece, of specially treated European maple. The treatment makes the wood darker, harder and more stable. It gives, combined with the big amount of brass, a supreme sound, and makes it look good. The oil treatment also contributes to the beautiful look, and that the feeling of wood is maintained. The back part is made of a lighter wood, called radiate. It is also treated with oil and has furthermore resonance cavities in order to give more sustain and reduce the weight.
Carried with a guitar strap the Rotator hangs very balanced, and does not feel heavy. Through the design of the back part, and the location of the security straplocks, the instrument is tilted a little towards you, which means that you can better see both fretboards, and gives you a good playing angle. Your right underarm has a good rest on the rounded back part. This is also the place, where you, with your right hand, grab hold before rotation. The left hand starts the rotation towards you, counter-clockwise, and the right hand brings the front part in place with a click. It is possible to play an open string amplified during the rotation.
