<p>An amplifier, such as a vacuum tube guitar amplifier, including a configurable preamplifier, power amplifier and/or power supply. Configuration of sections of the amplifier can be controlled by software, which can be updated directly on the amplifier though an editing interface, by downloading new configuration data from an external device or network, or by updating hardware-based cards or daughter-boards. The amplifier can store multiple circuit designs, and give users access to designs on demand, along with associated potentiometer and switch settings stored in 'patches', as well as allow real-time control over potentiometer settings via the amplifier's user interface, or external control via a communications interface. Global settings can also be configured to take into account factors such as type and rating of vacuum tubes. The same methodology can be applied to stand-alone preamplifiers or power amplifiers, solid state amplifiers, preamplifiers or power amplifiers.</p> |
