Abstract

In recent years, applying a triode tube to the guitar pedal as a signal modulator has been attracting considerable attention. The miniature tube 12AX7/ECC83 is still the key component for creating main sound properties of a guitar amplifier owing to its specific non-linear characteristics. Therefore, the attempts to incorporate the tube harmonic distortion sound to the pedal instead of solid-state circuit came out in the market. This paper describes a technique to generate the same harmonic spectrum focusing tube Crunch sound at 150V power supply voltage, which is half of conventional 300V. This voltage scaling contributes to reducing the battery power consumption of the tube guitar pedal to prolong the playing time.
