The Su MALEKKO Octave Fuzz effect pedal, featuring drive and volume adjustment. - Model Name: Octave Fuzz - Functions: Drive, Volume Adjustment - Accessories: Box, Instruction Manual - Color: Silver - Manufacturer: Sutty Corporation The Omicron series FUZZ is an old-school fuzz pedal that uses germanium diodes. This ultra-compact case packs a wide-range fuzz pedal. The VOL control adjusts the volume, and the DRIVE control varies the fuzz distortion. Furthermore, there is a 3-mode switch built into the left side of the pedal when you open the back cover. In position 1 (up), it becomes an octave fuzz, and in position 2 (down), it produces a scooped-midrange, "don-shari" sound. Both create classic, top-notch fuzz tones. Also, when the switch is in the center position, it produces a sound that is a blend of positions 1 and 2. Thank you for viewing.
