Unleash Fuzz-drenched Octave Fury
One of Fulltone’s most revered stompboxes, the Ultimate Octave is back — redesigned, refined, and as intense as ever. When it comes to ripping, zipper-like fuzz, few pedals can match the Ultimate Octave’s thick, harmonic-rich tones, which can morph between smooth sustain and gnarly saturation on a whim. Moreover, stomp on this fabulous fuzz box’s dedicated footswitch, and every note you play will be infused with an ear-grabbing, Hendrix-style octave-up effect. You also get Volume, Tone, and Fuzz knobs, as well as a Bright/Fat switch that toggles between mid-forward and mid-scooped textures. Handbuilt in the USA, the latest iteration of the Ultimate Octave boasts a smaller enclosure than its predecessor, along with top-mounted jacks and premium, full-size components. The Fulltone Ultimate Octave has garnered a sizable, well-earned cult following since its original unveiling. Don’t you think it’s time for you to experience its mammoth-size fuzz tones and screaming octave-up sounds for yourself?
