Add weight under every note you play.

Some riffs need the low end of a bass player who is not in the room. The UO300 adds two tones to your guitar: one octave and two octaves below the original. It is built for clear octave sounds with constant pitch, even for staccato playing.

Three levels, one blend

DIRECT sets the level of your original signal. OCT1 sets the tone one octave below, and OCT2 the tone two octaves below. Balance the three until the part sits where you want it.

Tune it to the instrument

The RANGE selector sets the pedal for HIGH, MID or LOW frequencies. That lets you use it with guitar, bass guitar or keyboard.

At your feet

A footswitch turns the effect on and off, and the blue ON/BATT LED lights when it is active. The same LED shows battery level. Run it on a 9 V battery or a 9 V power supply, both not included. It starts as soon as a jack goes into the input. Remove the jack when not in use to save the battery.
