An experimental project on a multiple-channel bandpass filter for stringed musical instrument timbre enhancement has provided some useful design data for a wide range of center frequencies with low-cost quad operational amplifier circuits. The apparatus has never been finished in a final cosmetic form, but the results of experimental breadboards may be of interest to audio technicians for related multiple-channel audio filters.
