Initial Response Acceleration (I.R.A.)

If you've ever played another guitarist's instrument and not been able to get the same sound, it's probably because you are playing a different style than what the guitar is used to. After playing the same guitar for years, the guitar adapts to the guitarist's playing style. It takes time for a new guitar to adapt to your own way of playing. Stress found between parts like finish, woods, body, neck, fingerboard, nut, bridge, etc., must be released before all of the parts can resonate together as an instrument. It takes time and a lot of playing for this to happen. Using I.R.A. technology, stresses like those between the finish and wood are released by applying specific vibrations to the completed guitars. Once this treatment is complete, the guitar responds accurately to the guitarist's performance and produces sound more easily. It also shortens the time needed for the guitar to adapt to your playing style and delivers excellent sustain.
