It has been long acknowledged by instrument makers and musicians the importance of regularly playing guitars or other stringed instruments to achieve and maintain their optimum tone and resonance. Regular, consistent play breathes life into an instrument while its tone develops producing a better sound, otherwise known as ''play-in''. It's been witnessed over centuries that playing an instrument keeps it "alive". Due to indispensable physical and dynamic mechanical properties, wood is the supreme material used to produce these instruments.
''Wood is just a monosyllabic word, but behind it there is a world of myths and miracles.'' (Theodor Heuss)
The sound characteristics of stringed instruments such as guitars are dependent on a number of factors including the complexity of the construction involving the mounting of different parts with individual vibration behaviours. The sound quality can be improved by regular playing, as mechanical wood properties implied in acoustical quality, especially the viscoelasticity (often referred to as damping) are dependent on exposure time to vibrations. Moisture content in wood also influences the vibration behaviour determining tone colour changes.
When the instrument is played, vibrations from the strings are transmitted to the various wood parts of the main body. Vibrations are changing wood properties of an acoustic or electric guitar at molecular level, affecting the way it responds. As a result, the instrument becomes more resonant, producing a richer sound with improved tone characteristics and sustain.
The best guitar tone and quality of sound output should start from the instrument itself, before any influence in the electric signal chain.
ROTONE is a mechanical strumming device for guitars acoustic resonance enhancement, developed for acoustic and electric guitars or similar stringed instruments. The guitars tone device creates vibrations simulating the playing in effect similarly to when the instrument is played by a musician.
Strumming accelerates the "play-in" process, enhancing the sustain and the quality of sound produced by instruments to achieve the best possible tone. After approximately 120 hours of strumming sessions, an increase in resonance, range, more refined and brighter tone can be expected due to an improved acoustic vibration response.
The device will modify the dynamic mechanical properties of wood in stringed instruments into a more acoustically ideal condition, by vibrating the instrument through continuous strumming, while allowing the chords to vibrate freely.
Direct, unaltered vibrations from the strings are transfered to the guitar wood structure, while a varied range of acoustic frequencies relating to the musical tones can be alternated during the conditioning treatment using a guitar capo.
