ABSTRACT:
A pickup responsive in all planes of vibration of a vibrating element of a musical instrument uses two transducers, each maximally responsive in a different plane of vibration. The transducer signals are dephased with respect to each other in order to reduce and possibly eliminate the additive and substractive tendencies of the common portion of the signals when they are combined to produce the pickup signal. The signals may be dephased using a phase shifting network or device, or by using different types of transducers (i.e.: position-sensing for the first transducer and velocity-sensing for the second transducer) which produce signals which are already dephased and thus only require to be combined in order to produce the claimed response.
