Electronic musical instruments as disclosed, include sensors to digitize and alter the sound using FSR sensors in the mouthpieces and other elements of the instrument to mimic the variations available in analog instruments.

A pickup for a guitar that has four (4) or more separate magnetic coils and selection means to select among the coil outputs. In some embodiments, the pickup is passive, not requiring an active pre-amplifier and voltage supply to shape the sound. In some embodiments, the selection means may be incremental or continuous, providing a wider degree to selectivity between and among the outputs of the separate coils.

An apparatus for enhancing the output of a stringed musical instrument having a plurality of offset substantially parallel strings, the apparatus comprising a pickup assembly having tapered poles so as to incrementally vary the relative volume of adjacent strings.

Embodiments disclosed herein describe systems and methods for asymmetrical bobbin configurations. Embodiments of asymmetrical bobbin configurations are configured to allow manufacturers and users to modify, adjust, change, etc. the tone of pickups. The asymmetrical bobbin configurations are configured to boost frequencies on strings on an instrument, wherein based on the configurations of the bobbins different frequencies may be modified.

A sound detection system of a musical instrument with vibrating parts includes at least a pair of sensors and a preamplification unit for processing the signal output from the two sensors along respective channels. At least one of the pair of sensors is a piezoelectric transducer and the other one of the pair of sensors is a different-type transducer. The preamplification unit includes, for each channel, an input stage, including an amplifier circuit and an equalization circuit, and an output stage including at least a weighted adder circuit and at least two volume controls with arbitrary logarithmic response curve. At least the input stage for the channel of the piezoelectric transducer is a charge amplifier circuit and at least one of the other input stages can be configured both as a charge amplifier and as non-inverting amplifier with high input impedance. The equalization circuit includes an RC circuit.

A magnetic pickup system comprising a magnetic pickup and a ferromagnetic tone shaper without electrical connections that is magnetically coupled and separately mounted from the pickup on a musical instrument with ferromagnetic strings.
