Abstract: Concept and ways are described of implementing a sound distortion circuit suitable for musical instruments, in particular, for electric guitars. Inputting an audio signal, low noise intrinsic to the circuit electronics is provided to the output. This type of noise, here referred to as electroacoustic noise, is produced by the interaction of the harmonic components of the audio signal with the natural ways by which sound and heat propagate in materials that make up the circuit components. The invention demonstrates that this type of noise, not foreseen by prior art, presides over the musical quality of sound even when artificially distorted, as is often required especially by guitarists. Compared to the best that is offered by comparable prior art equipment, the invention offers the musician greater freedom of tonal research and also greater ease of musical performance, thanks to the greater degree of intonation obtainable with the instrument.

Abstract: A system and method for producing feedback in a stringed musical instrument, especially in an electric guitar or bass guitar where a guitar amplifier simulator is used in lieu of a traditional amplifier and speaker, or other situations in which it is not convenient to induce a feedback. A transducer such as a small speaker is positioned against the head or body of the guitar. Sound from the guitar is provided to the speaker, and sound from the speaker causes the guitar strings to vibrate, which vibration is in turn picked up by the guitar's electronic pickup. An electronic circuit may be provided to introduce distortion into the audio signal sent to the speaker.

Abstract: A method for digitally processing audio signals to emulate the effects of vacuum tube amplifiers and preamplifiers, musical instrument amplification systems, and distortion effects. By use of an implicit numerical method to estimate the response of a parametrically-controlled non-linear transfer function, non-linear filters, and feedback elements, the dynamic behavior and distortion effects of tube amplification stages are simulated. This provides the capability to reproduce the desired sounds of vintage and modern tube amplifier systems and effects with the conveniences and control associated with digital signal processing systems and software.
