Abstract: An exemplary modular musical instrument amplification system may comprise a chassis including a power supply, an input gain stage, a control processor and a plurality of modular slots. The modular slots are configured to receive any of a plurality of preamplifier modules for establishing an electrical communication therewith. The input gain stage has a modifiable response behavior and is in signal amplifying communication between at least one instrument input jack and the modular slots. The control processor is preferably in control communication between the modular slots and the input gain stage. Each preamplifier module has a respective input stage profile associated therewith. The control processor may be configured for sensing the input stage profile of a preamplifier module received in an active modular slot, and setting the response behavior based, at least in part, upon the respective input stage profile.

Abstract: A low power amplifier architecture that employs a single-ended (single triode) push-pull (SEPP) vacuum tube and output transformer arrangement, and that cancels unwanted amplifier signal components such as hum and noise. The SEPP amplifier operates to cancel power supply ripple and local EMI induced noise in the output transformer by providing reverse polarity of the primary coils of the output transformer.

Abstract: A dynamic sensor regulator that provides a mechanism for introducing desirable tonal artifacts in component-based guitar amplifier systems by inducing voltage fluctuations into the power supply of a preamplifier. The dynamic sensor regulator comprises a regulator circuit, connected to an amplifier that is connected to a converter circuit that is connected to a variable control circuit. The amplifier includes a floating bias circuit that dynamically adjusts the bias state of an output driving amplifier in response to signal fluctuations of the regulator output signal. A transformer is connected to the amplifier output and once the transformer's saturation point has been reached, the saturation of the transformer increases proportionally with the amplifier's input signal while the regulated output signal remains constant, emulating amplifier overload and saturation.
