Learn About Harmonics by Means of the Vacuum Tube Guitar Amplifier

Document Thumbnail

Traditional electric guitar system is a typical analog sound generator with harmonics, which is composed of pickups and a vacuum tube amplifier. The colorful spectrum is created by controlling various non-linearity originated from biasing of the circuit elements, especially the triode vacuum tube of the head amplifier. It is also said that the sound changes with the tube manufacturers even though the same tube model number. In this paper, Marshall JCM800 2203 model (recognized as the industry benchmark) is employed to present that the system is one of the best tools for learning about harmonics distortion sound associated with the generation mechanism by measurement and SPICE simulation (SPICE: Simulation Program with Integrated Circuit Emphasis).
