We report the result of test that has given the acoustic excitation to the new guitar in the aging cell with using the Bach's cello suites. The sound quality effect of playing the guitar for five years is the same as one of the four weeks aging test with the high load. However, the too much aging gives the new guitar the adverse effects. In this time, we were able to have the good balance results with the light load aging. But there were few effects in the upper position sounds of the guitar. The sound range of the cello is not enough to the acoustic excitation of high frequency zone. So, we will try soon the aging test with playing the violin pieces.

<p>We have studied the sound quality improvement of the classical guitar. The running-in of really playing on the guitar as well as the manufacturing process of guitar gives the large influence to the sound quality. It is called an aging effect. It is important that the behavior of the aging effect is considered on the manufacturing process. But the result of over-aging treatment causes, sometimes, the poor sound quality. The mechanism of over-aging is open here.</p>
