ToneRite Mandolin

One of the secrets of great sounding vintage instruments is the fact that they have been played-in for thousands of hours.  

The ToneRite accelerates the play-in process by using a set of sub-sonic frequencies to simulate the same physics as long term playing.  

Simply attach the ToneRite whenever you are not playing and expect to hear a dramatic increase in resonance, balance and range after only a week's worth of use.  

Subsequent treatments will help maintain your new vintage sound!
