There’s nothing like the classic octave effect to give your guitar the ultimate load of super-thick, lush tone. The SO400 pedal generates an output an octave below single notes. By switching to its Polyphonic Octaves function, you can even super-size chords into bursting clusters.

This first-class pedal features two creative controls: Octave 1 plus a rotary knob switchable between Range / Octave 2 / Drive settings. You can also feed unprocessed signal out to other BEHRINGER processors with output level control via a separate Direct knob. But the Real Sound Modeling (RSM) processor with its state-of-the-art DSP technology is the actual star of the show, giving you sound quality fidelity found only in high-end studio processors. The unit includes separate Bass and Guitar inputs, separate Direct output, a shining blue LED to indicate the power status and battery condition plus an electronic footswitch, which preserves signal integrity in bypass mode. Use a 9 V battery or our BEHRINGER PSU-SB DC power supply to run the SO400 effects pedal wherever you like.

Make your tone go XXL—at the tap of a toe!
