AB  - It is well known that components of an electric guitar system contain even-harmonics properties inherently, such as vacuum tubes or Fuzz pedal feedback circuits. Furthermore, there are several popular pedals in the "Overdrive" category and the difference in timbers attributes to even-harmonics. However, it is difficult to identify the correlation between transfer characteristics and auditory nuances, which seems to involve psychoacoustic factors such as masking effect. In this study we developed a novel pedal that can continuously control the strength of even-harmonics and odd-harmonics, and clarified the high-order distortion effects from spectrum analysis of intermodulation distortion taking Loudness K-weighted full scale (LKFS) correction. This effector pedal must be a powerful tool for perceptual distortion analysis by using real instrument signal where masking effect occurs.
