摘要： An improved amplifier circuit which effectively combines two amplifier stages by utilizing two nested feedback loops so that an inverting amplifier topology is used with a FET input device, operating as a common source/emitter configuration cascoded by the inverting input of an opamp. The circuit operates as a non-inverting amplifier and is connnected to the drain or collector with local nested feedback to (a) independently control the loop gain, (b) linearize its own operation, and (c) control the stability of the circuit. Additional inputs can be summed using a non-inverting summing circuit. One application reduces distortion derived from a high impedance, capacitive input source.

摘要： A transducer for use with a musical instrument to transmit vibrations from the instrument to an amplifier has a weight, at least one sensor connected to the weight, an insulating layer covering the weight and the sensor, a substrate layer covering the insulating layer, an attachment device for mounting the transducer to the musical instrument and a cable mounted to the bas for connecting the transducer to an amplifier. One conductor of the cable is mounted to the weight and a ground shield of the cable is connected to the substrate. The transducer translates surface vibrations of the instrument into electrical signals that can then be amplified or recorded. The transducer has superior tonal qualities.

摘要： The present invention 10 has two components that provide the signal that is representative of the guitar sound, a primary pickup device 12 and a secondary pickup device 52. The primary device is the piezoelectric pickup 12 that is situated between the strings 18 beneath the saddle 14 of a stringed instrument 16. The primary device 12 is designed to detect the bulk of the sound as well as the tonal nuances. The primary device does not provide ambience. The secondary device 52 as used in one embodiment of the present invention makes use of the physically induced charge modulation properties along both the longitudinal and transverse axis of the interconnecting coax cable 52 that runs from the primary pickup 12 to the impedance changing preamplifier 36. This cable can simulate the ambience that could otherwise be generated from discrete microphones or reverberation devices. An optional pair of pickups 26 may be disposed outside the strings 18. Also, a compressible gasket 34 may be placed between the pickup 12 and saddle 14 and the pickup 12 and the bridge 22 to prevent air gaps thereinbetween.
