This is an octave fuzz overflowing with vintage character. It covers not only one octave up, but also two octaves down.
You can choose three types of octave settings: +1 or -1 and -2, or all up and down octaves to get thick vintage fuzz sounds. In addition, there is a tone control for +1 octave and a volume control for -2 octave.
Because the Trike Fuzz drives descending octave circuits combined in parallel with ascending octaves, you can create a versatile array of sounds unattainable by standard octave fuzz units.
