This classic Fuzz effect pedal not only produces the oscillator sound found in the Fuzz Factory, but also features an auto-wah filter and octave effect! The gain is even and coarse, producing a powerful sound with a solid sound pressure, and the sound is characterized by a powerful, gated edge and excellent separation. The output sound will elicit emotions and invite you to play wild and loud guitars! Another highlight of this product is the ability to create a variety of tones that combine auto-wah and octave sounds. The convenient controls on the pedal allow you to pinpoint exactly what you want to adjust, so you can create anything from a psychedelic sound with a strong auto-wah feel to a bitty sound with an emphasis on octaves, and really get creative! Not only is it a great weapon, but it has also been improved from the previous model "Infinity", making it a truly powerful product with a more powerful core and a sound image with excellent sound projection! Control "FREQUENCY"...This control allows you to change the main frequency band of the sound, and by turning it while playing, you can enjoy a theremin-like effect. "THRE"...You can adjust the dial tone. "SENS"...Turning it to the left changes it to an octave fuzz sound, and turning it to the right changes it to an auto-wah fuzz sound. "VOLUME"...You can adjust the overall volume. *Since the volume can easily become very loud, we recommend gradually increasing it from the lowest setting.Power supply: 9V battery or 9V center negative (Makino Kobo POWHER SUPPLY-M or BOSS 9V adapter recommended) *Please use a power supply equipped with a stabilizing circuit.
