We kept hearing the same issues - poor sound quality when the acoustic guitar is amplified, regardless of the amp or PA in use, and a loss of the natural guitar sound.
ReWave will never compromise tone to control feedback, Instead it allows your instrument to "breathe" naturally while enhancing the overall acoustic guitar tone. This is our quest and now it is finally available to you. You have to hear it to believe it!

Please check this video, and
you will hear the difference between acoustic guitars with and without the ReWave!!

We tapped into our design team's vast knowledge of professional audio engineers, music producers and product designers to create this wonderful product. What we discovered is, with the use of our Patent Pending of intake, exhaust technology, a mechanical compressor, EQ and the anti-feedback control system, the acoustic guitar would stabilize under heavy feedback conditions, sound natural, and exhibit an unbelievable sonic dynamic range. And Thus "ReWave" was born!!

The challenge with existing methods of post sound processes for acoustic guitars are that you have to repair tonal issues after the sound wave is amplified from acoustic energy to electric energy. This is challenging because the sound waves have then introduced muddy bass, harsh mids, shrill highs and feedback regeneration that your guitar can naturally produce. So, then you will have to use expensive electronic devices or plug-ins which will also implement hiss, white noise, pink noise and phase cancellation into the correction repair process, leaving you a very unmusical ,edgy unpleasant guitar tone. This happens because the acoustic guitar body has a natural phenomenon under the soundboard called bottle-necking, which is the collection of sound waves that continually get stuck under the bridge area of the guitar, right where the piezo pickup is usually mounted.

ReWave solves these issues without any compromise to your precious tone and is the first and only one on the market to do so. Through the use of our patent pending, interconnected set of sound processing systems, we were able to eliminate these problems before you amplify your acoustic guitar. Using a rubber plug can reduce feedback, but it always compromises your tone, dampens the soundboard and inevitably kills the sweet and natural sound of your acoustic guitar. If you are here chances are you have experienced all these issues and It's time to take control of your sound, it's time for TONE JUSTICE.

ReWave is the first and only Natural (non electronic) Preamp, Made for the serious musician!
