Patent ID: 8204254

Claim:
A method of amplifying music from an instrument using a vacuum tube amplifier comprises the steps of (a) determining a value of the music to be controlled or amplified, (b) inputting the value into a vacuum tube gain stage, (c) generating a first gain output by the vacuum tube gain stage, (d) inputting the first gain output into a distortion controller, (e) generating a controller output by the distortion controller, (f) inputting the controller output into a second vacuum tube gain stage, (g) generating a second gain output by the second vacuum tube gain stage, (h) inputting the second gain output into a passive 3-band audio filter for equalization control, (i) generating an equalized output by the passive 3-band audio filter for equalization control, (j) inputting the controller output into a third vacuum tube gain stage, (k) generating a third gain output by the third vacuum tube gain stage, (l) inputting the third gain output into a channel switcher, (m) generating an equalized output by the channel switcher, (n) when desired, inputting the equalized output generated from the step (i) or the step (m) into a reverb mixer, (o) generating a reverberated output by the reverb mixer, (p) inputting the reverberated output into a fourth vacuum tube gain stage, (q) generating a fourth gain output by the fourth vacuum tube gain stage, (r) inputting the fourth gain output into a volume controller, (s) generating a volume-controlled output by the volume controller, and (t) using the volume-controlled output as the vacuum tube amplifier output such that the control, amplification, or combinations thereof is introduced by the vacuum tube amplifier.
