A guitar pickup transforms the vibration of strings to the electric signals, and deliveres them to an amplifier. A piezo pickup has interference problem between strings. The paper aims to improve sound quality for an electro-acoustic guitar through the finite element analysis. Firstly the conventional pickup is modeled and analyzed with a commercial program called ANSYS. It is obvious that there exists interference between the strings. The structural modification of the pickup is performed, based on the beam theory. The modified structures are suggested, modeled and analyzed. Then the result are compared with those in the conventional pickup. It can be concluded that the interferences with the modified structures are much less than those with the conventional structure.
