A sustaining device is described for prolonging the vibration of the strings of a stringed musical instrument, such as an electric guitar having two or three electromagnetic pickups. The pickups are all low impedance transducers that can function either as pickups or driver transducers, depending on whether they are connected to the input of the instrument pickup amplifier or to the output of the sustainer amplifier, respectively. When a transducer is being used as a sustainer driver, it cannot be simultaneously used as a pickup. Different methods of selecting transducers to function as pickups or drivers are described. The transducers, having only hundreds of wire turns instead of the usual thousands of turns for common pickups, have a flat audio frequency response that can be modified to produce a multitude of common pickup sounds by manipulating the transducer resonance frequency, bandwidth, and amplifier gain.
A pickup-prioritized electromagnetic sustainer for an electric stringed musical instrument, wherein the strings of said instrument are stretched between an instrument bridge and a headstock at the end of the instrument neck, wherein said instrument has two low impedance electromagnetic low impedance electromagnetic transducers, wound with several hundred turns of wire, that function as string vibration pickups when said sustainer is placed into a standby state, wherein said low impedance electromagnetic transducers sense the vibrations of said strings and produce an audio signal voltage in response to said vibrations, and wherein a first said low impedance electromagnetic transducer is disposed near said instrument bridge and is called a bridge transducer, and wherein a second said transducer is disposed near said instrument neck and is called a neck transducer, wherein said instrument has an instrument output for said audio signal, said sustainer comprising:
A driver-prioritized electromagnetic sustainer for an electric stringed musical instrument, wherein the strings of said instrument are stretched between an instrument bridge and a headstock at the end of the instrument neck, wherein said instrument has three low impedance electromagnetic low impedance electromagnetic transducers that can function as pickups that sense the vibrations of said strings and produce an audio signal voltage in response to said vibrations, wherein a first said transducer is disposed near said instrument bridge and is called a bridge transducer, and wherein a second said transducer is disposed near said instrument neck and is called a neck transducer, and wherein a third transducer is disposed in between said bridge and neck low impedance electromagnetic transducers and is called a middle transducer, wherein said instrument has an instrument output, said sustainer comprising:
A driver-prioritized electromagnetic sustainer for an electric stringed musical instrument, hereinafter called instrument, wherein the strings of said instrument are stretched between an instrument bridge and a headstock at the end of the instrument neck, wherein said instrument has two low impedance electromagnetic transducers that function as pickups that sense the vibrations of said strings and produce an audio signal voltage in response to said vibrations, wherein a first said low impedance electromagnetic transducer is disposed near said instrument bridge and is called a bridge transducer, and a second said low impedance electromagnetic transducer is disposed near said instrument neck and is called a neck transducer, wherein said instrument has an instrument output, said sustainer comprising:
