Octava is an all-analog octave fuzz / frequency doubler featuring an on-board low pass Filter control that allows you to achieve singing octave up tones anywhere on the neck, without adjusting your guitar’s tone control. A front-end Drive and gushing Fuzz circuit add signal power and easily convert Octava to shoegazey fuzz pedal capable of producing devastating, full-wave rectified distortion. Use the Blend knob to mix the octave up effect on top of your dialed-in drive.
