The sound output from the audiovisual apparatus is inferior compared with the live performance. Information of music that the guitarist gave to the string can be measured by the 2 Dimensional Pickup devices we manufactured. Using the plucking information of guitar strings, we designed and constructed the Acoustic Guitar Playing System which can vibrate directly the bridge on the sound board of the guitar and can make guitar sound using the amplified power with the measured information of the 2 Dimensional Pickups.To make a comparison with the sound between our Acoustic Guitar Playing System and the same acoustic guitar itself, we experimented with the aid of the sweep sound, the theoretical guitar synthesized sound and the flamenco music sound. The result of comparisons is that the sound of the Acoustic Guitar Playing System was superior in the low frequency range, but inferior in the high frequency range.
