Our Mission

Guitar amplifiers still utilize vacuum tubes as a means to amplify an electric guitar. Many musicians prefer the sound produced by a vacuum tube amplifier versus a transistor or digital implementation amplifier. When driven into a nonlinear state, vacuum tubes will distort in a gradual way that is pleasing to the ear. By contrast, when a transistor is saturated, it can tend to an overall harsh distortion that is not pleasing to the ear. The quality of the produced sound is the primary advantage of the vacuum tube amplifier over modern transistor amplifiers. However, vacuum tubes are relatively bulky, dissipate a large amount of heat, and are susceptible to becoming microphonic, where the vacuum tubes mechanically vibrate producing undesired sound. Their physical size when compared to transistors is a major disadvantage. The physical size of a guitar amplifier and complementary audio components is an area ripe for improvement. The speaker cabinet used for these amplifiers is large in size as well as the effects units that complement these amplifiers. The goal is to model and simulate the characteristics of these components in a digital environment in a compact form that allows portability and ease of use. By implementing everything in the digital domain, the user is afforded a more compact, portable solution to their overall system. The digital domain would also allow the user to obtain more amplifier, speaker, and effects modules than would previously be attainable due to size and lack of available capital.
