One of the secrets of great tone is continually playing-in your instrument. The ToneRite® is the world"s most advanced and premier play-in device. Utilizing the same physics as you playing your instrument, the ToneRite® can significantly accelerate the play-in process and provide you with increased tone, playability and balance. The ToneRite® makes all of this available in a nearly silent, high quality, and portable manner. The secret behind the ToneRite® is its ability to continually produce and efficiently transfer vibrational energy into an instrument, safely recreating and magnifying the physics that occur naturally while playing. This stimulation produces a change to the integrated components within an instrument and increases their ability to resonate together as a whole. The result is added volume and instruments that are easier to play with a sound that is more full and balanced. Not only will your instrument sound better but the notes themselves will come easier, allowing you to play more difficult passages with less fatigue.
