6. The instrument according to claim 1 , wherein said multi-channel processing system comprises a plurality of signal processors, wherein each processor of said plurality of signal processors is associated with a separate transducer of said plurality of vibration-sensing transducers, and wherein each processor of said plurality of signal processors generate a processed output signal in response to electrical transducer signals generated by said associated separate transducer.
1. A stringed instrument comprising: an elongated instrument body; a plurality of strings coupled to said instrument body, wherein each string of said plurality of strings is under tension and spans a distance over said instrument body; a plurality of bridges, wherein each bridge of said plurality of bridges is associated with a separate string of said plurality of strings, and wherein each bridge of said plurality of bridges is slideably adjustable over a substantial portion of said span over said instrument body; a plurality of vibration-sensing transducers, wherein each transducer of said plurality of vibration-sensing transducers is associated with a separate string of said plurality of strings, and wherein each transducer of said plurality of vibration-sensing transducers generates a distinct electrical transducer signal responsive to vibrations of said associated separate string; and an interface adapted to provide transducer signals generated by said plurality of vibration-sensing transducers to a multi-channel processing system.
