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!
This is a 220V version. Do take note. Thank you.
