The Behringer UO300 Ultra Octaver effects pedal lets you underpin your guitar or bass playing with beefy low-end tones. With dedicated knobs to dial in the perfect amount of octave-down effect, the UO300 thickens up your sound in a way that commands attention. It's equipped to generate notes one and two octaves lower than what you play, adding a powerful dimension to your riffs, leads and chords.

Shape the Octave Effect to Your Taste

First, use the dedicated Range control to specify whether you want to add depth to the high, middle or low frequencies of your guitar or bass. Then dial in the amount of your original tone with the Direct knob. Finally, blend in the lower Oct1 and Oct2 tones to achieve the ideal balance of fat low end and articulate pick attack. The UO300 gives you the flexibility to customize the octave effect exactly how you want it.

Works Great With Guitar, Bass and Keys

The UO300 isn't just for beefing up guitar—it also sounds fantastic with bass guitar and keyboards. The octave effect really makes synth tones come alive. Simply plug your instrument into the 1/4" input and run the 1/4" output into your amp or interface. The UO300 enhances any instrument with its special blend of low octave tones.

Add Thickness to Any Rig

The Behringer UO300 Ultra Octaver pedal makes it easy to add low-end thickness to your guitar or bass rig. Dialing in the right amount of octave effect is simple with the dedicated controls. Whether you want to subtly widen your tone or dramatically beef it up, the UO300 has you covered.
