The octave can be turned off by the toggle switch, turning it into a warmer and thicker fuzz pedal. The best way to achieve a well pronounced octave sound is by lowering the Pre gain and the tone control on your instrument. The balance between the Pre and Honey is the key to achieve a variety of sounds. On the octave mode, things can get really nasty, splashy and gated. It's great for high gain leads, specially when played above the 12th fret. With a little less HONEY you can get that "purple haze" tone. At low gain settings it can produce "ring modulator" overtones, great for textures. With the octave off it's a whole different pedal, producing a warmer and thicker fuzz tone, making it more versatile and "chord friendly". The OctaHive was based on the 1970's Tycobrahe Octavia and it can produce classic and modern sounds. A great addition to every pedal board.
